Bio-fortification and isotopic labelling of Se metabolites in onions and carrots following foliar application of Se and 77Se
Provedor de dados: 21
Autores: Kapolna, Emese; Laursen, Kristian Holst; Husted, Søren; Larsen, Erik H.
The aims were to bio-fortify onions by foliar application of selenium (Se) and to intrinsically label bioactive Se-metabolites in onion and carrot by enriched, stable77Se for use in human physiological studies. Onion bulbs and leaves were enriched in Se by repeated foliar spraying of 10 or 100 μg Se mL-1 solutions of sodium selenite (Se(IV)) or sodium selenate (Se(VI)). ICP-MS analysis of onion leaves and bulbs showed that the Se concentration was enhanced by up to a factor of approximately 50 and 200 in bulbs and leaves, respectively. HPLC-ICP-MS analysis of proteolytic plant extracts showed that foliar application of Se(IV) gave rise to bio-synthesis of a higher fraction of the desired organic Se species and was better tolerated by the plants than...

Avaliação da glicemia, do tempo de ingestão de concentrado e movimentos mastigatórios após jejum induzido em equinos
Provedor de dados: 195
Autores: Sanchez, P. J.; Silva, C. A.; Alves Jr., A. H.; Silva, C. A.; Marion, R. A.; Abib, R. N.
O marcante crescimento e fortalecimento do mercado, bem como a profissionalização da equinocultura têm possibilitado que procedimentos clínicos e cirúrgicos sejam realizados com maior frequência pelos profissionais médicos veterinários de equideos. Alguns protocolos exigem que os animais sejam submetidos à período de jejum prévio. CUNNINGHAM e KLEIN (2007) citam que o jejum é um fator de estresse e pode acarretar em hipoglicemia. Os equinos são herbívoros não ruminantes, monogástricos de hábitos alimentares constantes, extremamente seletivos e que, quando submetidos à alimentação concentrada e peletizada, realizam de 60 a 80 movimentos mastigatórios por minuto (FRAPE, 2007; BRANDI e FURTADO, 2009).

Hérnia diagragmática congê nita em felinorelato de caso
Provedor de dados: 195
Autores: Souza, Mary Anne Rodrigues de; Souza, Fádua Tawana Reis; Jesus, Fátima Barreto de.
O presente trabalho relata um caso de hérnia diafragmática congênita em um felino macho, sem raça definida, com três anos de idade, atendido na Clínica Veterinária Clinipet, localizada na cidade de Aracaju/SE. A queixa principal era que o animal havia saído e voltou apresentando uma dificuldade respiratória mais intensa que a normal. Durante a anamnese foi constatado que, desde filhote, o felino fora magro, longilíneo para os padrões de um felino, apático, não responsivo ao ambiente de forma que não interagia, não vocalizava e evitava fazer esforços.

Autores: Correia, L.; Malliagros, L. V.; Brasil, T.; Pires, B. C.; Jaeger, L. H.; Carvalho-Costa, F. A.; Lilenbaum, W.
&amp;nbsp;Bovine leptospirosis is characterized mainly by reproductive problems associated with infections by strains of serogroup Sejroe. Pathogenic strains belonging to same serogroup could present differences in pathogenicity, suggesting existence of unknown molecular mechanisms involved in virulence. Furthermore, it is known that subculture of strains can lead to attenuation of virulence by changes in protein coding genes.

Avaliação do efeito da inclusão de Saccharomyces cerevisae sobre a digestibilidade aparente total em dieta para equinos
Provedor de dados: 195
Autores: Taran, F. M.; Gonzaga, I. V.; Françoso, R.; Centini, T. N.; Rodrigues, F. P.; Moreira, C. G.; Gobesso, A. A.
Os carboidratos nas dietas de equinos podem alcançar 75% da ração, no entanto, é necessário que haja equilíbrio entre carboidratos estruturais e não estruturais. O excesso de carboidratos hidrolisáveis e de rápida fermentação podem exceder o intestino delgado e atingir o ceco, levando ao desenvolvimento excessivo da microbiota e fermentações indesejáveis. Uma estratégia é o uso de leveduras vivas como a Saccharomyces cerevisiae (SC), pois recentes pesquisas demonstraram que a adição de leveduras vivas podem limitar o desenvolvimento de modificações indesejáveis na microbiota do intestino do cavalo, juntamente com um balanceamento entre volumoso e concentrado.

Urges Smith to reread his last letter [not extant] where Smith will find that Banks did not draw parallels between Smith and [Richard] Salisbury. Had Banks known how deep the quarrel between Smith and Salisbury had become he would never have undertaken the "hopeless task" of effecting a reconciliation, and now relinquishes it. Refers Smith to his advice in last letter, viz to refrain from personal altercations but by no means avoid potential discussion. Remarks that whilst he does not "feel the esteem for Salisbury [he] once did" he does not "despise his indefatigable industry".

The aim was to assess heterosis in a set of 16 summer-squash hybrids, and evaluate the combining capacity of the respective parental lines, which differed as to the degree of parthenocarpy and resistance to PRSV-W (Papaya Ringspot Virus-Watermelon strain). The hybrids were obtained using a partial diallel cross design (4 x 4). The lines of parental group I were 1 = ABX-037G-77-03-05-01-01-bulk, 2 = ABX-037G-77-03-05-03-10-bulk, 3 = ABX-037G77-03-05-01-04-bulk and 4 = ABX-037G-77-03-05-05-01-bulk, and of group II, 1' = ABX-037G-77-03-05-04-08-bulk, 2' = ABX-037G-77-03-05-02-11-bulk, 3' = Clarice and 4' = Caserta.

The objective of this study was to obtain estimates of genetic and phenotypic parameters for egg mass of meat quails and also to propose an optimal age for selection of birds through the egg mass. The data used in this study came from 3,503 female meat quails (UFV1: 1.811 quails; UFV2: 1.692 quails) of the Poultry Breeding Program from Universidade Federal de Viçosa. The traits examined were egg mass in partial periods until 77, 112, 147 and 182 days, and egg mass in the total period of 407 days by the use of single and bi-trait animal models. For the genetic group UFV1, the heritability values for the periods were high: 0.58, 0.59, 0.57, 0.59 and 0.24 (until 77, 112, 147,182 and 407 days, respectively).

Additive and non-additive genetic effects for fruit traits of ornamental pepper
Provedor de dados: 75
Autores: Pessoa,Angela Maria dos S; Rêgo,Elizanilda R do; Rêgo,Maílson M do.
ABSTRACT Pepper plants can be used as ornamental ones due to the contrasting traits of plants, flowers, and especially fruits. This variability can be exploited in genetic improvement programs aiming at identifying superior genotypes and obtaining hybrids. This work aimed to select parental and hybrid individuals through diallel analysis for fruit traits in Capsicum annuum. Seven pepper genotypes were crossed, and eleven fruit-related quantitative traits were evaluated. The data were subjected to diallel analysis using Griffing’s Method 1 (fixed model). There was a predominance of additive genetic effects on the fruit traits of ornamental pepper plants. Genotypes UFPB77.3 and UFPB390 are indicated as parents for the improvement of ornamental pepper plants,...

Provedor de dados: 77
Autores: Garba,S. H; Numan,A. I; Mishara,I. G.
Anthropometric measurements, such as craniofacial forms especially in the first days after birth are important for the assessment of neonatal health status and results obtained from such measurements are used in pediatrics, orofacial surgery and diagnostic comprehension between patient and normal populations. There is no published literature about the types of head and face shapes in the Kanuri and Babur/Bura newborns of Maiduguri metropolis. Henee, this study was undertaken to document the various craniofacial forms of newborns of Maiduguri metropolis. Head length, head width, head circumference, face length, face width, prosopic and cephalicindices were measured in 120 newborns of the Maiduguri metropolis.

Identification of informative performance traits in swine using principal component analysis
Provedor de dados: 45
Autores: Barbosa,L.; Lopes,P.S.; Regazzi,A.J.; Guimarães,S.E.F.; Torres,R.A.
Using principal component analysis, records of 435 animals from an F2 swine population were used to identity independent and informative variables of economically important performance. The following performance traits were recorded: litter size at birth (BL), litter size at weaning (WL), teat number (TN), birth weight (BW), weight at 21 (W21), 42 (W42), 63 (W63) and 77 (W77) days of age, average daily gain (ADG), feed intake (FI) and feed:gain ratio (FGR) from 77 to 105 days of age. Six principal components expressed variation lower than 0.7 (eigen values lower than 0.7) suggesting that six variables could be discarded with little information loss. The discarded variables present significant simple linear correlation with the retained variables. Retaining...

Autores: Oplustil,Carmen Paz; Leite,Olavo H.M.; Oliveira,Marilia S.; Sinto,Sumiko I.; Uip,David E.; Boulos,Marcos; Mendes,Caio F.
This study was done to determine the occurrence of mycobacteria in the bloodstreams of patients with fever and advanced AIDS in a Brazilian hospital. We also verified the capability of an automated method for recovering these bacteria. During a period of 19 months, 254 patients with AIDS were evaluated. Blood cultures were generally submitted in pairs and drawn separately. Blood cultures were processed by the BACTEC 460TB System (Becton Dickinson Microbiology Systems, Sparks, MD), using the Bactec 13A media (Becton Dickinson Microbiology Systems, Sparks, MD). Of the 530 vials submitted, 77 (14.5%) from 41 (16%) patients were positive. Mycobacterium avium complex was recovered from 45 (58.4%) of the 77 positive vials, corresponding to 22 (53.6%) patients...

Bacteria isolated from Korean black raspberry vinegar with low biogenic amine production in wine
Provedor de dados: 58
Autores: Song,Nho-Eul; Cho,Hyoun-Suk; Baik,Sang-Ho.
Abstract A high concentration of histamine, one of the biogenic amines (BAs) usually found in fermented foods, can cause undesirable physiological side effects in sensitive humans. The objective of this study is to isolate indigenous Acetobacter strains from naturally fermented Bokbunja vinegar in Korea with reduced histamine production during starter fermentation. Further, we examined its physiological and biochemical properties, including BA synthesis. The obtained strain MBA-77, identified as Acetobacter aceti by 16S rDNA homology and biochemical analysis and named A. aceti MBA-77. A. aceti MBA-77 showed optimal acidity % production at pH 5; the optimal temperature was 25 °C. When we prepared and examined the BAs synthesis spectrum during the...

Filamentous fungi and media for cellulase production in solid state cultures
Provedor de dados: 58
Autores: Kilikian,B.V.; Afonso,L.C.; Souza,T.F.C.; Ferreira,R.G.; Pinheiro,I.R.
Cellulase production was evaluated in two reference strains (T. reesei Rut-C30 and T. reesei QM9414), two strains isolated from a sugarcane cultivation area (Trichoderma sp. IPT778 and T. harzianum rifai IPT821) and one strain isolated in a program for biodiversity preservation in São Paulo state (Myceliophthora thermophila M77). Solid state cultures were performed using sugarcane bagasse (C), wheat bran (W) and/or soybean bran (S). The highest FPA was 10.6 U/gdm for M77 in SC (10:90) at 80% moisture, which was 4.4 times higher than production in pure W. C was a strong inducer of cellulase production, given that the production level of 6.1 U/gdm in WC (40:60) was 2.5 times higher than in pure W for strain M77; T. reesei Rut-C30 did not respond as strongly...

Incoordenação de membros posteriores em equinos associados à toxoplasmose - relato de caso
Provedor de dados: 195
Autores: Santos, João Paulo de Almeida Ferreira dos; Nasciutti, Nayara Resende; Oliveira, Patricia Magalhães de; Anjos, Carolina; Garcia, Felipe Gonçalves.
O Toxoplasma gondii é um parasita que tem como hospedeiro definitivo todos os felídeos, e como hospedeiros intermediários os mamíferos, dentre eles o próprio felídeo, o homem e o equino. A contaminação nos herbívoros ocorre pela ingestão de gramíneas e ração contaminadas pelo oocisto. Foi atendido no Hospital Veterinário da Universidade Federal de Uberlândia um equino, macho, quarto de milha, de dois anos e meio de idade, com histórico de fezes pastosas, emagrecimento e incoordenação nos membros posteriores. Ficava com uma égua em um piquete, que morreu dez dias antes com os mesmo sinais clínicos, sendo a alimentação a base de pasto e sal mineral e água em cocho. No hemograma foi constatado anemia, sendo também realizado diagnóstico diferencial para anemia...

Aspectos do controle da mosca-dos-chifres e manejo de resistência.
Provedor de dados: 14
Autores: BARROS, A. T. M. de.
A mosca-dos-chifres é uma praga relativamente recente na bovinocultura brasileira, introduzida na região Centro-Oeste há pouco mais de uma década. Desde então, seu controle tem sido dependente do uso de produtos inseticidas, o que tem sido realizado, de modo geral, de forma abusiva e indiscriminada em todo o país. Ao longo dos anos, o controle químico deste e de outros ectoparasitas tem levado à seleção de populações resistentes, reduzindo a eficácia dos produtos, mantendo perdas na produtividade e encarecendo os custos do manejo sanitário e, em última análise, da produção.

Custo de produção em pecuária de corte em 2009, no Pantanal de Aquidauana (MS).
Provedor de dados: 14
Autores: CARVALHO, T. B. de; ABREU, U. G. P. de; ALMEIDA, B. da S.; ZEN, S. de.
Conforme os cálculos feitos com os dados levantados na região de Aquidauana, a receita da pecuária de corte consegue cobrir o custo operacional efetivo (COE) e o custo operacional total (COT), é suficiente para abater a depreciação, mas insuficiente para cobrir o capital investido (CI). Este fato indica que a atividade é um investimento sustentável e lucrativo, no curto e no médio prazo, mas não no longo prazo, pois o produtor não conseguirá remunerar seu capital investido.

A Case of Unilateral Fenestration and Duplication of the External Jugular Vein
Provedor de dados: 77
Autores: Snoj,Ziga; Cvetko,Erika.
The external jugular vein is increasingly being utilized as the recipient vein in head and neck free tissue transfers, and for cannulation in order to conduct diagnostic procedures or intravenous therapies. The variations in the patterns of its course, and knowledge of them, are therefore important. We report on a unique and previously non-described unilateral fenestration and duplication of the external jugular vein found during the neck dissection of a 77-year-old female cadaver. Embryological evaluation and clinical implications of the anomaly are described. Clinicians and surgeons performing neck vascular or reconstructive surgery should be aware of this variation of the external jugular vein in the hope of preventing inadvertent injury.

Bilateral Origin of the Testicular Arteries from the Lower Polar Accessory Renal Arteries
Provedor de dados: 77
Autores: Panagouli,Eleni; Lolis,Evangelos; Venieratos,Dionysios.
The gonadal arteries (testicular or ovarian arteries) emerge normally from the lateral aspect of the abdominal aorta, a little inferior to the renal arteries. Several other sites of origin of these arteries have been recorded with the renal and accessory renal arteries being the most common. In the present case report, the testicular arteries originated from the lower polar accessory renal arteries in both sides. The testicular veins followed had the usual origin and course, while an accessory renal vein was observed only in the right side. These anomalies were combined with an abnormal left ureter exiting from the lower pole of the kidney. Only one male cadaver among 77 adult human cadavers of Caucasian origin presented this set of variations (frequency:...

Cephalic index is important parameter for deciding race and sex of an individual whose identity is unknown. Cephalic index and head shape are greatly affected by geographical, sex, age and racial factors. Present study aimed at working out cephalic index in Indian students. 100 students were taken as subjects and head length, head breadth were measured. Indian males had mean cephalic index of 77.92 and they were mesocephalic and females had mean cephalic index of 80.85 and they were brachycephalic. The comparison was statistically significant. The data is utmost important in forensic medicine, anthropology and in genetics.

Autores: KOJIMA, Yuka; CHIBA, Shiori; HORIUCHI, Noriyuki; KOBAYASHI, Yoshiyasu; INOKUMA, Hisashi; 堀内, 雅之; 古林, 与志安; 猪熊, 壽.
S100B in cerebrospinal fluid (CSF-S100B) was measured in calves with 20 neurologic and 21 non-neurologic diseases to clarify its utility as a biomarker for neurologic diseases. The median CSF-S100B value in the neurologic disease group (43.0 ng/ml) was significantly higher than that in the non-neurologic disease group (10.2 ng/ml). As CSF-S100B levels in calves with neurologic diseases widely differed, the utility of CSF-S100B as a diagnostic marker for neurologic diseases in cattle remains inconclusive.

Organic Fruit Production in Europe

Autores: Weibel, Franco.
PART I: SHORT HISTORY OF ORGANIC FARMING  The organic fruit production in Europe is not only a matter of statistics, regulations and tables but also has a meaningful historical background. So as an introduction, we can take a brief excursion back to the roots and the evolution of organic farming. (The following text is closely—but not entirely—based on an overview article of Gunter Vogt, 2000a). Organic farming’s origins in the first decades of the 20th century need to be understood in the context of five main aspects:

PORK PRODUCTION COSTS: A COMPARISON OF MAJOR PORK EXPORTING COUNTRIES
Provedor de dados: 31
Autores: Brewer,   Clarence; Kliebenstein,   James B.; Hayenga,   Marvin L.
Cost of production information for major pork exporting countries was collected from producer record systems.  The cost of production data for farrow-to-finish operations was reviewed and transformed in comparable categories.  The cost comparisons show that like-kind Midwestern U.S. producers have approximate cost differences of $6.00 per cwt marketed.  The international farrow-to-finish cost of production per cwt for 1995 is as follows: Western Canada (38.97), large Midwest U.S. (39.03), average Midwest U.S. (43.28), Eastern Canada (46.97), the Netherlands (74.58), and Denmark (77.59).  Depending on size and location of operation, cost of production in 1995, ranged from 38.97 to 77.59 cwt marketed.

Autores: Villalba Andrade, Mateo.
El tema de la presente investigación es analizar los efectos del cambio institucional que se dio en el sector energético, durante el periodo de estudio, y explorar el papel que jugaron los grupos de interés en este sector. Dichas agrupaciones se denominan coaliciones distributivas de acuerdo al término acuñado por Mancur Olson  (distributive coalitions). De esta manera, la presente investigación busca aportar, desde los postulados de la Nueva Economía Institucional (NEI), elementos que permitan explicar por qué se dan estos resultados tan inconvenientes para el desarrollo del país y el mejoramiento de las condiciones de vida de la población.

De acuerdo al psicoanálisis, un aspecto constitutivo del sujeto es el lenguaje, que establece entre el ser humano y su entorno una brecha, mediante la intermediación de representaciones mentales conceptuales surgidas de sus vínculos maternos y paternos. Pero el sujeto aprende a romper los amarres y ataduras impuestas por las conductas, normas y reglas de su cultura. De allí que su posibilidad de crecimiento como sujeto ocurre con su capacidad imaginativa y su aptitud para recrearse un universo simbólico.

Ecuador : entre la ilusión y la maldición del petróleo (Tema Central).
Provedor de dados: 122
Autores: Acosta, Alberto.
El ingreso del Ecuador, como productor petrolero de importancia, ocurrida en la década de los setenta del siglo XX, se constituyó en una fuente de financiamiento a tras de la cual se intentaron reformas y modernizaciones del Estado, en particular la fallida política de sustitución de importaciones. Con el decaimiento de los precios, el agresivo endeudamiento y los ajustes forzados para su pago, el petróleo dejó de ser un motor de la economía para convertirse en el “sujeto de pago” de la deuda. Su actual explotación acarrea, además, serios riesgos para la frágil ecología amazónica.

Argopecten circularis (Sowerby, 1835) fecunddity was estimated during spawnings of February-March 1989 and March-May 1990 in Bahía Concepción, Baja California sur, México. In general, the number of oocytes released during the spawning of Argopecten circularis were potentially relatad to shell height. The calculated average oocyte wet weight during the maturity period was 8.9033x10^-8 g. Spawning ocurred ¡n individuáis 44 to 77 mm in height. The highest fecundity occurred ¡n bivalves 58 to 77 mm ¡n height. Mean fecundity obtained for all heigts by regression analysis during spawning in February-march 1989 was 12, 102, 243 oocytes. In April-May of the same year, there were 17, 917, 006 oocytes, and during March-May 1990, 16, 938, 117 oocytes.

O experimento foi realizado no Vale do Submédio São Francisco, nos ciclos de produção de novembro de 2009 a março de 2010 e de junho a setembro de 2010, em delineamento experimental de blocos ao acaso, com quatro repetições constituídas por cinco cachos. Os cachos foram coletados, periodicamente, a partir do início da maturação, que correspondeu, na 'Isabel Precoce', aos 54, 61, 68, 71, 74 e 77 dias após a frutificação (DAF), no primeiro ciclo, e aos 49, 56, 63, 67, 71, 74 e 77 DAF, no segundo. Na 'BRS Cora', os cachos foram coletados aos 61, 68, 71, 74, 77 e 82 DAF, no...

Autores: Báez,E; Franchini,E; Ramírez-Campillo,R; Cañas-Jamett,R; Herrera,T; Burgos-Jara,C; Henríquez-Olguín,C.
Human performance efficiency and effectiveness in different sports depend to a large extent on the size, weight and proportion of the physique of the athlete. The aim of this study was to identify morphological characteristics of Brazilian Jiu-Jitsu (BJJ) athletes. The sample consisted of 25 highly trained male athletes who were classified according to their fighting style; guard fighter (GF) vs. pass fighter (PF). The athletes were assessed for somatotype, body composition and proportionality. For the whole group of athletes the somatotype was 2.23±0.68, 6.33±1.14, and 1.75±0.87 for endomorph, mesomorph and ectomorph components, respectively. Muscle and adipose tissue percentages were 52.34±2.15% and 19.30±2.51%, respectively. PF were significantly more...

Synergistic Induction of NR4A Orphan Nuclear Receptors by LPS and cAMP in Murine Macrophage Cells
Provedor de dados: 17
Autores: Harish Shandilya; Sidney M. Morris.
Although NR4A orphan nuclear receptors have been implicated in inflammatory gene expression and atherosclerosis, there is little information regarding their regulation by combinations of stimuli likely to be found in vivo, such as LPS and inducers of cAMP. LPS rapidly induced Nur77 and NOR1 mRNAs but had little effect on expression of Nurr1 mRNA. All three NR4As were rapidly induced by 8-bromo-cAMP and remained elevated for at least 8 h. Maximum induction of NOR1 by 8-bromo-cAMP was much greater than with LPS, but maximum induction of Nur77 was similar with both agents. Whereas Nurr1 mRNA had very little response to LPS, it was strongly induced by 8-bromo-cAMP, and Nurr1 mRNA levels remained elevated for at least 20 h. The combination of 8-bromo-cAMP and...

ABSTRACT: The use of herbicides is widespread in weed management, and adjuvants are added to the spray solution to improve the effectiveness of applications. The goal was to evaluate the influence of adjuvants added to the herbicides saflufenacil and glyphosate, isolated or in combination, and the effects on the surface tension, deposition and effectiveness in post-emergence applications to control Conyza sumatrensis. Experiments were conducted completely randomized experimental design to evaluate surface tension (TS), deposition and herbicide effectiveness. The treatments were glyphosate, glyphosate + saflufenacil and saflufenacil with or without the adjuvants Natur’al óleo®, Assist®, Aterbane®, Sillwet L-77 and Dash HC® (surface tension). For the...

Lesões ortopédicas são comuns em equinos devido ao tipo de esforços que são constantemente submetidos. Nestes animais, injúrias por sobrecarga e trabalho repetido são comumente encontradas na articulação metacarpofalangeana e suas estruturas associadas. O ferrageamento corretivo pode ser utilizado a fim de controlar as lesões sofridas por tendões e ligamentos, no entanto, mesmo tratando-se de um método terapêutico comumente utilizado, o efeito sobre a articulação metacarpofalangeana ainda permanece impreciso.

Relato de caso: utilização da gabapetina para analgesia em equinos
Provedor de dados: 195
Autores: Penachio, Daniel da Silva; Matiello, J. A.; Oseliero, L. R.; Osiro, J.H. H; Soares, P. N.B.; Moura, A. R.
A gabapentina é um análogo do neurotransmissor inibitório GABA (ácido gama-aminobutírico), utilizada em medicina humana em casos de epilepsia e neuralgia. Em pequenos animais, é empregada como anticonvulsivante. Acreditava-se que a gabapentina atuasse em receptores gaba, porém estudos negaram essa teoria. Outras possibilidades são a ligação com canais de cálcio voltagem-dependentes em membrana pré-sinaptica, atenuando a transmissão nervosa, e a alteração no metabolismo de aminoácidos no sistema nervoso central. Embora o mecanismo de ação desse fármaco permaneça incerto, atribuise a ela o potencial de proporcionar atividade ansiolítica, analgésica, sedativa e/ ou tranquilizante, relaxamento muscular e também anticonvulsivante em equinos.

Sr and Nd isotopic characteristics of 1.77-1.58 Ga rift-related granites and volcanics of the Goiás tin province, central Brazil
Provedor de dados: 42
Autores: PIMENTEL,MÁRCIO M.; BOTELHO,NILSON F.
Supracrustal rocks of the Araí Group, together with coeval A-type granites represent a ca. 1.77-1.58 Ga old continental rift in Brazil. Two granite families are identified: the older (1.77 Ga) group forms small undeformed plutons, and the younger granites (ca. 1.58 Ga) constitute larger, deformed plutons. Sr-Nd isotopic data for these rocks indicate that the magmatism is mostly product of re-melting of Paleoproterozoic sialic crust. Initial Sr ratios for both granite families are ca 0.726 and 0.720. Most TDM model ages are between 2.58 and 1.80 Ga. epsilonND(T) values are between +3.6 and -11.9. Araí volcanics are bimodal, with basalts and dacites/rhyolites interlayered with continental sediments. The felsic volcanics show Nd isotopic characteristics which...

Isolation, sequencing and phylogenetic analysis of the hemagglutinin, neuraminidase and nucleoprotein genes of the Chilean equine influenza virus subtypes H7N7 and H3N8
Provedor de dados: 48
Autores: Müller,Ilse; Jaureguiberry,Beltrán; Valenzuela,Pablo D.T.
We report here on the isolation and sequencing of the hemagglutinin, neuraminidase and nucleoprotein genes of the Chilean equine influenza virus subtypes H7N7 (A&amp;#8260;equi-1&amp;#8260;Santiago&amp;#8260;77, Sa77) and H3N8 (A&amp;#8260;equi-2&amp;#8260;Santiago&amp;#8260;85, Sa85) . The sequences obtained allowed a variability analysis, which indicated significant differences when compared with other isolates. We found that Chilean isolates are more similar to the North American variety than to European isolates. Isolate Sa77 is a good candidate for inclusion in a vaccine as it is the latest isolate of the subtype H7N7 and is probably better-adapted to the equine host. Isolate Sa85, of subtype H3N8, also appears to be a good candidate since it has no...

Autores: Sarto,Marcos Vinicius Mansano; Bassegio,Doglas; Rosolem,Ciro Antonio; Sarto,Jaqueline Rocha Wobeto.
ABSTRACT Safflower (Carthamus tinctorius L.) is a commercial seed crop grown for its good yield of high-quality oil. It is tolerant to water stress but may be sensitive to soil compaction. The aim of this study was to assess safflower growth under different degrees of soil compaction at depths of 0.15 m to 0.20 m. The experiment was carried out in PVC pots constructed from three rings. Five levels of penetration resistance (0.20, 0.33, 0.50, 0.93, and 1.77 MPa) were applied in the intermediate ring, and two safflower genotypes, IMA-4904 and IMA-2106, were examined. There was no difference between safflower genotypes with respect to their resistance to soil compaction, which reduced root length density in the compacted layer and changed the root...

Autores: Dias, Emely Gabrielle Pereira; Pellizzaro, Maysa; Garcia, Rita de Cassia Maria; Biondo, Alexander Welker.
O combate entre galos é uma prática antiga e os primeiros relatos datam de mais de 4.000 anos atrás. Desde então a prática se tornou comum e persiste atualmente, com mercado de produtos para os combates ativo e acessível, como a venda de ovos galados pela internet. Animais de diversas raças são treinados para utilizar esporas e outros utensílios. As rinhas de galos foram proibidas no Brasil há 80 anos, com a publicação do Decreto Federal 24.645/1934, que entendeu a prática como causadora de maus tratos aos animais envolvidos. A Lei federal de crimes ambientais (Lei 9605/1998) estabelece como crime qualquer ato de maus tratos e é utilizada para punir os infratores. A prática é ilegal e criminosa, porém diversos regulamentos de associações dos praticantes de...

Provedor de dados: 14
Autores: DIAS FILHO, M. B.; LOPES, M. J. dos S.; FREITAS, M. V. de; ASSIS, G. M. L. de.
O comportamento de cinco acessos de Arachis pintoi (39, 57, 77, 83 e 90) foi comparado, durante 15 dias, em plantas cultivadas em vasos, sob alagamento ou em solo bem drenado. O objetivo foi classificar esses acessos quanto à tolerância relativa ao alagamento do solo e avaliar o desempenho agronômico desses acessos, independentemente do regime hídrico. O decréscimo no índice SPAD, em resposta ao alagamento do solo, foi maior nos acessos 77, 39 e 90 e menor no acesso 83. O percentual de redução na produção de massa seca da parte aérea das plantas alagadas foi maior nos acessos 90 e 57 e menor no acesso 39. O alagamento do solo reduziu a floração no acesso 90. Nos demais acessos não foi possível encontrar diferenças entre tratamentos para esse parâmetro....

Provedor de dados: 77
Autores: Leigh,Olufisayo Oluwadamilare; Raheem,Ayobami Kabir; Oluwadamilare Olugbuyiro,Joseph Adebisi.
The characteristics of exfoliated vaginal cells and vulvar biometry following estrus synchronization via two injections of 5mg Lutalyse® administered 7 days apart were investigated with the aim of their possible use to predict estrus in six adult WAD does. Four adult WAD bucks recently passed as satisfactory potential breeders were also involved in the study. The animals were maintained on 12% crude protein concentrate, greens and fresh water ad libitum. All measurements in the does were taken at an interval of 24 hours for six days beginning with the day of 2nd Lutalyse® injection. The does were introduced to the bucks 48 hours after the 2nd dose of Lutalyse® and separated from them after the 6th day. The 72-96 and 96-120 hours vaginal smears of 5 does...

Provedor de dados: 77
Autores: Eboh,D. E. O; Obaroefe,M.
The pterion is an important landmark on the side of the skull as it overlies both the anterior branch of the middle meningeal artery and the lateral cerebral fissure intracranially. The study was carried out to determine the pterion types and define its distances to some neighboring structures in dry human skulls of Southern Nigerians. The study comprised 50 dry human skulls of unknown sex and age obtained from selected Nigerian Universities. Sutural patterns of the pterion on both sides of each skull based on the description of Murphy (1956), were observed and recorded. Distances of the pterion to neighboring structures were also measured using digital vernial caliper. Data obtained were subjected to statistical analysis using descriptive statistics and...

Provedor de dados: 89
Autores: Alves,WJ; Viana,GS; Barreto,SLT; Muniz,JCL; Hannas,MI; Silva,AD; Arnaut,PR; Barros,VRMS.
ABSTRACT This study was conducted to estimate the dig. valine to lysine (Val:Lys) ideal ratio for meat-type quails from 15 to 35 d of age. A total of 385, 15-day-old not sexed quails, were randomly assigned to five treatments, each one seven times replicated with eleven quails per experimental unit. Experimental treatments consisted of five dig. Val:Lys ratios (0.65; 0.70; 0.75; 0.80 and 0.85). Ideal dig. Val:Lys ratio was estimated using polynomial regression and linear broken-line regression model. Significant effect was considered when p≤0.05. Feed conversion ratio was not affected by dig. Val:Lys ratios in any of the assessed phases. From 15 to 21 d of age Val:Lys ratios increased linearly feed intake, weight gain and body weight. From 15 to 28 d of...

ABSTRACT: Asian citrus psyllid, Diaphorina citri, is considered the most important citrus pest worldwide, as it transmits Huanglongbing – serious citrus disease. New efficient and sustainable strategies to control this pest have been investigated and the use of entomopathogenic fungi has become a promising alternative. The objective of this study was to evaluate the effects of adjuvants a) Tween 80 at 0.01 % (v/v); b) Silwet L77 at 0.025 % (v/v) and c) KBRAdj at 0.075 % (v/v) on adhesion, germination and pathogenicity of Isaria fumosorosea ESALQ-1296(5 × 106 conidia mL–1). Female adults of D. citri used in this experiment were sprayed on Citrus limonia seedlings. The sprayed insects were analyzed through scanning electron microscopy (SEM) to identify the...

Uso de indicadores internos na avaliação da digestibilidade aparente de alimentos para gatos: comparação de métodos
Provedor de dados: 65
Autores: Carciofí,Aulus Cavalieri; Prada,Flávio; Mori,Clara Satsuki.
Os ensaios de digestibilidade são importantes para o desenvolvimento e avaliação de rações animais. Estes podem ser realizados através do método convencional, ou de coleta total, e pelo método dos indicadores, dividindo-se os últimos em externos (adicionados ao alimento), e internos (presentes naturalmente no alimento). Com a finalidade de buscar métodos alternativos, menos trabalhosos e com resultado seguro, o presente estudo objetivou comparar o método de coleta total com o dos indicadores para a determinação da digestibilidade de rações para gato doméstico, testando como indicadores a fibra bruta (FB) e a fibra em detergente ácido (FDA). Utilizou-se 4 gatos (2 machos e 2 fêmeas) adultos jovens, mantidos em gaiolas metabólicas individuais durante 30 dias...

Anomalous Origin of Obturator Artery from the Internal Iliac Artery
Provedor de dados: 77
Autores: Kumar,Dinesh; Rath,Gayatri.
Obturator arteryis frequently a branch of anterior division of internal iliac artery or one of the parietal branches of internal iliac artery. But it has attracted attention of pelvic surgeons and anatomists and radiologists because of the high frequency of the variation in its course and origin. The present report demonstrates obturator artery to be arising from the posterior division of internal iliac artery out of 316 pelvises, a rare observation in Indian population. The variation is correlated developmentally and its clinical implications are also discussed

Homoplasies, Consistency Index and the Complexity of Morphological Evolution: Catfishes as a Case Study for General Discussions on Phylogeny and Macroevolution
Provedor de dados: 77
Autores: Diogo,Rui.
Catfishes constitute a highly diversified, cosmopolitan group that represents about one third of all freshwater fishes and is one of the most diverse Vertebrate taxa. The detailed study of the Siluriformes can, thus, provide useful data, and illustrative examples, for broader discussions on general phylogeny and macroevolution. In this short note I briefly expose how the study of this remarkably diverse group of fishes reveals an example of highly homoplasic, complex 'mosaic' morphological evolution

Hermaphroditism in Marine Mussel Perumytilus purpuratus (Lamarck, 1819), (Mollusca: Mytilidae)
Provedor de dados: 77
Autores: Montenegro Villalobos,Diana; Olivares Paz,Alberto; González,María Teresa.
Marine bivalves are essentially gonochoric species. However, some occasional hermaphrodites specimens can be found. A histological description of two (among 179) hermaphrodites of the marine mussel Perumytilus purpuratus (Lamarck, 1819) that were collected in San Jorge Bay (24S) is given. The low proportion of hermaphrodites suggests that P. purpuratus hermaphroditism could be an accidental phenomenon; nevertheless other causes are also discussed in the present study.

Autores: Squarcia,Silvia Margarita; Sidorkewicj,Nora Silvia; Casanave,Emma Beatriz.
The morphology and morphometry of the cranial bones of Chaetophractus villosus were studied. The skull components are morphologically similar between adults of both sexes, and follow the generalized pattern for most of described dasypodids. The morphometric analysis, however, demonstrated that the bones lying in the rostrocaudal plane are mostly longest in females, determining higher values of the total, basal and condilobasal lengths of the skull, which are the main variables that contribute to a sexual dimorphism in this species

Morphology and Histological Annual Changes of the Oviduct of Chaetophractus villosus (Mammalia, Xenarthra, Dasypodidae)
Provedor de dados: 77
Autores: Codón,Stella Maris; Casanave,Emma Beatriz.
The morphological features of the oviduct in the armadillo Chaetophractus villosus (Desmarest, 1804) were studied. In the simple columnar epithelium, ciliated cells, secretory cells, and cells of the bottom of the folds are described. The most remarkable findings are the increase in number of ciliated cells, when present, from the fimbriae to the uterus, being the isthmus practically lined by ciliated cells, and that secretory cells are more abundant in the apical zone of the ampulla and fimbriae, than in the isthmus. Morphological changes along the year in the different portions are described.

Three Rare Variations in the Course of the Gonadal Artery
Provedor de dados: 77
Autores: Bandopadhyay,Manimay; Saha,Anubha.
The gonadal arteries, lateral branches of the abdominal aorta, usually arise distal to the renal vessels. Knowledge of the origin and course of them, particularly their relationships with renal vessels, are important for uncomplicated surgical procedures on the posterior abdominal wall. So the relationship of the testicular artery and renal vessels were studied in 80 cadavers in Calcutta National Medical College, India and detected three rare variations. We have discussed the possible clinical implications and embryological explanation with review of literature of those variations.

Radiographical and Macroscopical Visualization of Fourth Molars: a Report of Four Cases in Maxilla
Provedor de dados: 77
Autores: Fuentes,Ramón; Borie,Eduardo; Beltrán,Víctor.
Supernumerary teeth are defined as the existence of a higher number of teeth in relation to normal dental formula. The development of supernumerary teeth can happen at different times of the life and can be detected either, clinically or radiographically. The relation between supernumerary teeth and nonsyndromic cases have been reported once in a while in the literature. In this report are presented four cases of nonsyndromic patients with fourth molars in the maxilla, which were described macroscopically and radiographically.

Provedor de dados: 77
Autores: Duque Parra,Jorge Eduardo; Barco Ríos,John; Morales Parra,Genaro.
La vivisección es un procedimiento exploratorio del ser vivo, que a lo largo de la historia de la humanidad se ha practicado de manera invasiva, tanto en seres humanos como en animales, con el fin de visualizar la morfología y su correlación con la función orgánica. Este procedimiento evolucionó con el descubrimiento y utilización de agentes anestésicos y, posteriormente, con la tecnología de imágenes funcionales no invasivas para el ser vivo, con el propósito de comprender más los aspectos funcionales que los estructurales.

The parenchyma is organized morphologically as lobular restricted spermatogonial testis. Spermiogenesis in this species is characterized by four morphological stages of development (spermatids S1 through S4). The mature spermatids and spermatozoa heads are situated at the periphery of the cyst surrounded by the cytoplasm of the Sertoli cells. The germ cell's ultrastructure and spermatogenesis in P. caudimaculatus are very similar to that of other poeciliids.

Looped External Iliac Artery: a Case Report
Provedor de dados: 77
Autores: Nayak B,Satheesha; Kumar,Naveen; Shetty,Surekha D; Guru,Anitha.
Variations of the external iliac artery are very rare. We found a rare variation in the left external iliac artery. The artery was long and formed a characteristic loop. The loop was found in the lesser pelvis in close relation to the obturator nerve. This loop may compress obturator nerve and vessels. The knowledge of this loop might be important for gynaecologists, orthopaedic surgeons and urologists since it may be involved in surgeries of hip, ovary and prostate.

Structural and Ultrastructural Aspects of Folliculogenesis in Didelphis albiventris, the South-American Opossum
Provedor de dados: 77
Autores: Cesario,Maria Dalva; Matheus,Selma M. Michelin.
The ovarian histology, the structural and the ultrastructural characteristics of the folliculogenesis in Didelphis albiventris were described in detail. Recent studies suggest that methatherian mammals have unusual reproductive cycle but there are few informations regarding the marsupials reproductive life. Despite of the opossum folliculogenesis pattern resembles methatherian and eutherian pattern in many aspects, the analysis shows some peculiar features of the oocyte structure and ultrastructure that make available new data on the reproductive biology of marsupials.

Gross and Histologic Evaluation of Abdominal Adhesions Associated with Chromic Catgut and Polypropylene Sutured Enteropexies in Dog
Provedor de dados: 77
Autores: Akinrinmade,J. F; Lawal,A. O.
The gross and histologic patterns of abdominal adhesions formed by the use of chromic catgut and polypropylene suture materials were evaluated in dogs. Gross and histologic examinations did not reveal significant difference (p&gt;0.05) in the degree of adhesions observed at enteropexy sites in both suture materials. The use of polypropylene with superior suture qualities should be considered instead of chromic catgut for procedures in which adhesion is desired in the dog.

Analysis of non-compliances in the organic certification system in Turkey
Provedor de dados: 21
Autores: Zanoli, Raffaele; Gambelli, Danilo; Bruschi, Viola.
Organic farming in Turkey is experiencing a strong growth in recent years, with a particular attention to export towards Europe. International and domestic trade opportunities require an efficient control system for organic products. In this paper we analyse the data from inspections of two European control bodies in Turkish farms to analyse risk patterns of non-compliance with the organic regulation. A proportion test is performed to identify the types of crops that are more likely related to non-compliant operators.

Controle alternativo de Colletotrichum acutatum agente causal da queda prematura dos frutos cítricos
Provedor de dados: 94
Autores: Kupper,Katia Cristina; Bellotte,José Antonio Miranda; Goes,Antonio de.
A queda prematura dos frutos cítricos (QPFC), causada por Colletotrichum acutatum, dados os grandes prejuízos que têm causado aos produtores, constitui-se numa doença de grande importância econômica. O controle da doença é feito predominantemente mediante uso de fungicidas, que eleva o custo de produção e afeta negativamente o meio ambiente. Diante disso, este trabalho teve por objetivo buscar um método alternativo de controle da QPFC, mediante o uso de agentes de biocontrole ou de biofertilizantes. Diferentes concentrações de biofertilizantes (originários de duas fontes distintas e denominados de Bio1 e Bio 2); três isolados de Bacillus subtilis (ACB-69; 72 e 77) e três isolados de Trichoderma spp. (ACB-14; 37 e 39) foram testados, isoladamente ou em...

Provedor de dados: 97
Autores: Ramos-Jiliberto,Rodrigo; Hoecker-Escuti,Francisco; Mena-Lorca,Jaime.
In this work we discuss the ecological and mathematical significance of system's dimension in continuous-time population dynamics models. We show how the system's dimension reflects the ecological assumptions and affects both the spectrum of dynamic output and mathematical tractability of the models. We stress that the model dimension is not always the same as the number of state-variables, and we also present conditions under which the system's dimension is altered

COMPARATIVE ASSESSMENT BETWEEN PER-PIXEL AND OBJECT-ORIENTED FOR MAPPING LAND COVER AND USE
Provedor de dados: 70
Autores: Prudente,Victor H. R.; Silva,Bruno B. da; Johann,Jerry A.; Mercante,Erivelto; Oldoni,Lucas V.
ABSTRACT: The traditional per-pixel classification methods consider only spectral information, and may be limited. Object-based classifiers, however, also consider shape and texture, firstly segmenting the image, and then classifying individual objects. Thus, a Geographic Object-Based Image Analysis (GEOBIA) was compared in conjunction with data mining techniques and a traditional per-pixel method. A cut of Landsat-8, bands 2 to 7, orbit/point 223/77, located between the municipalities of Cascavel, Corbélia, Cafelândia and Tupãssi, in the west part of the state of Paraná, from 12/18/2013 was used. In the GEOBIA approach was realized image segmentation, spatial and spectral attribute extraction, and classification using the decision tree supervised...

The genus Arachis (Fabaceae) native to South America, contains 80 species divided into nine sections, three of which contain species of special economic importance such as the cultivated peanut (Arachis hypogaea), belonging to the section Arachis, and some perennial forage species from sections Caulorrhizae and Rhizomatosae. We used microsatellite markers to assay genetic variability among 77 accessions of four species from section Rhizomatosae, the diploid Arachis burkartii (2n = 2x = 20) and the tetraploid Arachis glabrata, Arachis pseudovillosa and Arachis nitida (2n = 4x = 40). A total of 249 alleles were found in the fifteen loci analyzed and a high degree of intra and interspecific polymorphism was detected. The lowest intraspecific variation...

We used four microsatellite loci (Fca08, Fca45, Fca77 and Fca96) from the domestic cat, Felis catus, to investigate genetic variability in specimens of Herpailurus yagouaroundi (jaguarundi, otter cat, eyra), Puma concolor (cougar, mountain lion, puma) and Panthera onca (jaguar) held in various Brazilian zoos. Samples of DNA from the cats were PCR amplified and then sequenced before being analyzed using the CERVUS program. Our results show a mean polymorphic information content (PIC) of 0.83 for H. yagouaroundi, 0.66 for P. concolor and 0.69 for P. onca and a mean of 10.3 alleles for the Fca08 locus, 5.3 for Fca 45, 9 for Fca 77 and 14 for Fca 96. These results indicate a relatively high level of genetic diversity for the specimens studied.

Autores: MIRANDA, J. I.
O objetivo deste documento é mostrar o potencial da integração de um sistema de informações geográficas (SIG) com um modelo de probabilidade, usando a distribuição de Poisson, para espacializar variáveis discretas. Modelos estatísticos são ferramentas importantes no estudo de variáveis ambientais, principalmente com a crescente importância da valoração do capital ambiental. A distribuição do Poisson é um bom modelo estatístico para manejo de variáveis discretas, pois mostra seu comportamento. Um passo posterior seria saber como essas variáveis se comportam no espaço, mostrando sua distribuição espacial. Nesse caso, os sistemas de informações geográficas (SIG) são bastante eficientes (Miranda, 2005). Para testar o uso de ambas as ferramentas e mostrar sua...

A produção de pequenos ruminantes tem apresentado um ciclo de crescimento mundial nos últimos anos. No Brasil, a atividade vem se consolidando com um enorme potencial de crescimento e expansão para diferentes ecossistemas, contudo, a especialização da produção depende, entre outros fatores, dos pré-requisitos de saúde e bem-estar animal. Os aspectos ligados a sanidade de rebanho na criação de caprinos e ovinos estão relacionados a inúmeros fatores determinantes da relação saúde/doença. Assim, consideram-se os aspectos relacionados ao manejo animal (controle zootécnico, nutrição, sanidade, reprodução e instalações) dependentes de controle a partir de medidas preventivas; e outros, porém, independentes de controle, como os determinados por diferentes...

Determinação do sexo da Tuvira Gymnotus sp. através da análise de imagem de ultra-som
Provedor de dados: 14
Autores: ROTTA, M. A.; PEDROSO, M. F.; ACORCI, L. C.
A tuvira (Gymnotus sp.) é um peixe muito conhecido no Pantanal por ser amplamente utilizado como isca viva pela pesca esportiva. Visto os problemas inerentes à sua coleta na natureza, como degradação ambiental e as condições desumanas de trabalho, faz-se necessário buscar alternativas para sua produção, como a criação em cativeiro. Entretanto, ainda não há uma técnica simples e não invasiva para a sexagem deste peixe. Deste modo, este trabalho tem por objetivo verificar a possibilidade de se utilizar a ultra-sonografia na determinação do sexo da tuvira. Foram avaliados 100 reprodutores coletados nos viveiros de reprodutores, os quais foram submetidos à análise individual de ultra-som utilizando-se um aparelho portátil (ALOKA C.O. LTD.

Three oyster samplers, collected in 1976, 77 and 78 have beer grown, each one after 3 differents densities in order to determine the influence of the load of breeding over growth and improvement of quality of oysters. The results show that quality of oysters is rapidly altered when the density of breeding increases and that gametogenesis physiolical prevails over growth, particularly for older oyster. A variation of the date of "détroquage" (oysters off supports that collect spat) will be determined, according to spat collecting and speed of spat growth. We are here suggesting a "production"coefficient.

Autores: Loots, Christophe; Vaz, Sandrine; Planque, Benjamin; Koubbi, Philippe.
The spatial distributions of spawning population of North Sea plaice and whiting were studied using geostatistical analyses. Variograms were computed each year since 1980 on abundance data of spawning adults using the first quarter data from the International Bottom Trawl Survey. Maps of spatial distribution of spawning adults were produced using kriging interpolation. For both species, distributions of spawning adults were in agreement with historical spawning grounds previously described from location of their eggs. This showed that spawning adults distribution may be used to infer the distribution of both plaice during its spawning peak and whiting at the beginning of its spawning period. Both species were strongly spatially structured with abundances...

Anatomic Variations of Extrahepatic Bile Ducts and Evaluation of the Length of Ducts Composing the Cystohepatic Triangle
Provedor de dados: 77
Autores: Cachoeira,Eduardo; Rivas,Antonio; Gabrielli,Carla.
It is of paramount importance for surgeons to have a thorough knowledge of the normal anatomy of the extrahepatic bile ducts and its variations due to the high frequency with which they perform in this anatomic site. The cystohepatic triangle, or Calot's Triangle, is bound by the cystic duct, common hepatic duct, and the hepatic border; therefore, its surface area depends on the conformation of these ducts and is closely linked to surgical procedures performed in this region. It has been reported that the length and the position of these ducts may be related to the formation of bile duct stones, Mirizzi's syndrome, and bile duct cancer. Thus, the present work aims to analyze the configuration of the extrahepatic biliary tree and its possible variations, as...

Provedor de dados: 77
Autores: Kavoi,Boniface M; Jameela,Hassanali.
Morphometric parameters of olfactory brain components show species-dependent variations. However, the association of these parameters with olfactory function vis-à-vis ecological and evolutionary behaviors is poorly understood. In this study, a morphometric analysis of the olfactory bulb, tract and stria was carried out in three ecologically diverse animals comprising humans (primate), dogs (carnivore) and goats (herbivore) to elucidate differences in morphometry in relation to olfactory function. Using formalin-fixed brains, volumes and linear measurements of the olfactory structures were determined and correlated with those of cerebrum and the whole brain. The volume of the olfactory bulb was greatest in dogs, followed by goats and humans and constituted...

The muscles can perform the same function in a specific segment (muscles of fast and slow contraction), and at the same time be antagonistic in relation to muscular action (flexors or extensors). The present research aimed to study the morphology, frequency and metabolism of fiber types and the contractile characteristics of extensor and flexors muscles of rabbit. We studied muscles anterior tibialis (AT), flexor digitorum supeficialis (FDS), extensor digitorum longus (EDL) and posterior tibialis (PT). The muscles were submitted to the techniques HE, NADH-TR and myofibrillar ATPase. In EDL and PT extensor muscles, the frequencies of red (SO + FOG) and white fibers (FG) were 68.77% and 31.23% versus 58.87% and 41.13%, respectively. In the AT and FDS flexor...

Características Morfológicas de la Retina del Calderón Común (Globicephala melas; Traill, 1809) y su Relación con el Hábitat
Provedor de dados: 77
Autores: Mengual,R; Segovia,Y; García,M.
Existe una estrecha relación entre las características morfológicas de los sistemas sensoriales, su funcionamiento y el hábitat al que están adaptados los organismos. En este sentido, de todos los mamíferos marinos estudiados, los cetáceos son los que más profundamente han modificado su estructura y fisiología ocular por su estrecha adaptación a una vida exclusivamente acuática. Para aportar más datos a la literatura, el objetivo de este trabajo es describir morfológicamente la retina de la ballena piloto a través de técnicas de microscopia óptica, con el fin de relacionarla con su adaptación al medio acuático.

The disease mutation A77V in Ryanodine receptor RyR2 induces changes in energy conduction pathways in the protein
Provedor de dados: 17
Autores: Burak Erman; Nazan Walpoth.
Energetically responsive residues of the 217 amino acid N-terminal domain of the cardiac Ryanodine receptor RyR2 are identified by a simple elastic net model. These residues lie along a hydrogen bonded path through the protein. The evolutionarily conserved residues of the protein are all located on this path or in its close proximity. All of the residues of the path are either located on the two Mir domains of the protein or are hydrogen bonded to them. Two calcium binding residues, E171 and E173, are proposed as potential binding residues, based on insights gained from the elastic net analysis of another calcium channel receptor, the inositol 1,4,5-triphosphate receptor, IP3R. Analysis of the disease causing A77V mutated RyR2 showed that the path is...

Bovine dilated cardiomyopathy (DCM) is an autosomal recessive genetic disorder causing congestive heart failure and subsequent death. Recently, a nonsense mutation c.343C&gt;T in the bovine optic atrophy 3 (OPA3) gene had been reported to cause the DCM in Holstein cattle in Switzerland. However, the mutation has not been confirmed in bovine DCM outside Switzerland. Nine Holstein Friesian cows that were macroscopically and histologically diagnosed with or suspected of DCM and 12 control cows kept in Japan were tested for the mutation. The mutation surrounding OPA3 DNA fragment was amplified by PCR and subjected to direct sequences. The homogeneous c.343C&gt;T mutation was proved to occur in all the affected cows and not in the control cows. The present...

Detection of monoclonal integration of bovine leukemia virus proviral DNA as a malignant marker in two enzootic bovine leukosis cases with difficult clinical diagnosis
Provedor de dados: 19
Autores: MIURA, Saori; HORIUCHI, Noriyuki; MATSUMOTO, Kotaro; KOBAYASHI, Yoshiyasu; KAWAZU, Shin-ichiro; INOKUMA, Hisashi.
Monoclonal integration of bovine leukemia virus (BLV) proviral DNA into bovine genomes was detected in peripheral blood from two clinical cases of enzootic bovine leukosis (EBL) without enlargement of superficial lymph nodes. A BLV-specific probe hybridized with 1 to 3 EcoRI and HindIII fragments in these 2 atypical EBL cattle by Southern blotting and hybridization, as well as in 3 typical EBL cattle. The probe also hybridized to a large number of EcoRI and HindIII fragments in 5 cattle with persistent leukosis. These results suggest that the detection of monoclonal integration of BLV provirus into the host genome may serve as a marker of monoclonal proliferation and malignancy in difficult to diagnose EBL cattle.

We investigated the concentration of the bacterial endotoxin lipopolysaccharide (LPS) in the blood, ovarian follicular fluid and uterine fluid of a clinical case of bovine metritis. A 2-year-old lactating Holstein cow exhibited continuous fever &gt;39.5°C for more than 2 weeks after normal calving. The cow produced a fetid, watery, red-brown uterine discharge from the vagina and was diagnosed with metritis. The LPS concentrations in plasma and uterine fluid were 0.94 and 6.34 endotoxin units (EU)/ml, respectively. One of seven follicles showed an extremely high level of LPS (12.40 EU/ml) compared to the other follicles (0.62–0.97 EU/ml). These results might suggest the presence of high concentration of LPS in follicles in cows with postpartum metritis.

Degeneration of the optic pathway has been reported in various animal species including cattle. We experienced a case of bilateral optic tract degeneration characterized by severe gliosis in a Japanese black cattle without any obvious visual defects. To evaluate the significance, pathological nature and pathogenesis of the lesions, we examined the optic pathway in 60 cattle (41 Japanese black, 13 Holstein and 6 crossbreed) with or without ocular abnormalities. None of these animals had optic canal stenosis. Degenerative changes with severe gliosis in the optic pathway, which includes the optic nerve, optic chiasm and optic tract, were only observed in 8 Japanese black cattle with or without ocular abnormalities. Furthermore, strong immunoreactivity of...

Infectious bursal disease (IBD) is characterized by immunosuppression due to the depletion of lymphocytes in the atrophied bursa of Fabricius (BF). We have sometimes encountered contradictory findings: chickens infected with the vaccine IBD virus (IBDV) strain have sometimes exhibited a highly atrophied BF, but not immunosuppression. In this study, chickens administered vaccine or wild-type strains of IBDV were later vaccinated with the B1 strain of the Newcastle disease virus (NDV). Bursal changes were examined histologically with a focus on the bursal follicle. The immunoreactivity to NDV was also evaluated with the hemagglutination inhibition test. In gross examination, we observed a few chickens with a severely atrophied BF in vaccine...

Autores: Horn, Karin; Ono, Kenichiro; Heydorn, Alfred Otto.
This paper describes a standard method for in vitro excystation of sporocysts of S.capracanis, S.hircicanis, S.ovicanis and S.arieticanis. A standard pretreatment was performed by 20 minutes preincubation of sporocysts in aqueous sodium hypochlorite (NaOCl) solution of 6% or 8% at room temperature. Then, sporocysts were washed 5 times in distilled water and were incubated for one hour at 39OC in excystation fluid consisting of RPMI 1640 medium, 10% PCS and 15% bovine bile. Additional sonication of pretreated sporocysts increased excystation rates as compared to not sonicated controls. Excystation rates for 1-9 months old sporocysts were 77% for S.capracanis, 77% for S.hircicanis, 72% for S.arieticanis and 92% for S.ovicanis. Sporozoite suspension as...

Bovine babesiosis is a livestock disease known to cause economic losses in endemic areas. The apicomplexan parasite Babesia bovis is able to invade and destroy the host’s erythrocytes leading to the serious pathologies of the disease, such as anemia and hemoglobinuria. Understanding the egress mechanisms of this parasite is therefore a key step to develop new therapeutic strategies. In this study, the possible involvement of Ca2+ in the egress of B. bovis merozoites from infected erythrocytes was investigated. Egress was artificially induced in vitro using calcium ionophore A23187 and thapsigargin to increase Ca2+ concentration in the cytosol of the parasite cells. The increased intracellular Ca2+ concentration following these treatments was confirmed...

An 11-year-old Holstein-Friesian cow exhibited anorexia and jaundice. A large mass was found in the liver during necropsy. Macroscopically, the mass was composed of dark red multilobular tissue and a centrally located abscess, which was connected to the hepatic duct. Histologically, the mass consisted of proliferation of small neoplastic cells and was demarcated from the hepatic parenchyma by a thick region of granulation tissue. The neoplastic cells were predominantly arranged in solid sheets, but they also formed blood-filled cancellous structures, and proliferating foci were seen around blood vessels. Periodic acid-Schiff reaction demonstrated that a fine basement membrane-like structure surrounded the neoplastic cells. Immunohistochemically, the...

Screening for ketosis using multiple logistic regression based on milk yield and composition
Provedor de dados: 19
Autores: KAYANO, Mitsunori; KATAOKA, Tomoko; 茅野, 光範.
Multiple logistic regression was applied to milk yield and composition data for 632 records of healthy cows and 61 records of ketotic cows in Hokkaido, Japan. The purpose was to diagnose ketosis based on milk yield and composition, simultaneously. The cows were divided into two groups: (1) multiparous, including 314 healthy cows and 45 ketotic cows and (2) primiparous, including 318 healthy cows and 16 ketotic cows, since nutritional status, milk yield and composition are affected by parity. Multiple logistic regression was applied to these groups separately. For multiparous cows, milk yield (kg/day/cow) and protein-to-fat (P/F) ratio in milk were significant factors (P&lt;0.05) for the diagnosis of ketosis. For primiparous cows, lactose content (%), solid...

Provedor de dados: 21
Autores: Weibel, F. P.; Lemcke, B.; Monzelio, U.; Giordano, I.; Kloss, B.
With field trials over 3 years in a commercial organic orchard in Switzerland we have tested the efficacy of Armicarb® (potassium-bi-carbonate) for flower thinning in organic apple production. Over time, Armicarb was tested on 11 cultivars, at different application periods, in different concentrations, and always in comparison to other agents that are already allowed for thinning in organic fruit production in the European Union as e.g. lime sulphur, molasses, mechanical ropethinner or combinations of methods. Armicarb proved to be an efficient and reliable thinning agent with an efficacy similar to the now recommended methods with rope device, molasses or lime sulphur but has the advantage to be an environmentally very friendly product.

Provedor de dados: 90
Autores: Gama,Marcos André Piedade; Matos,Gilson Sergio Bastos de; Silva,George Rodrigues da; Brasil,Edilson Carvalho; Nunes,Otiniel Ferreira.
The use of SMP pH to estimate the potential acidity (H + Al) is more practical than the method of 0.5 mol L-1 calcium acetate for routine laboratory analyses. The objective was to fit an equation to estimate the H + Al from SMP pH values of soils of the State of Pará. From various regions of the state, 177 soil samples were collected, in which the SMP pH was determined in 0.01 mol L-1 CaCl2 solution and H + Al in 0.5 mol L-1 calcium acetate and the results were related by regression analysis. The equation H + Al = 77.77 + 20.61 SMP pH - 1.435 SMP pH² (R² = 0.90) expressed the H + Al values (in cmol c dm-3) best. When the SMP pH values were used in equations referring to other regions or states in Brazil, the H +Al values were over- or underestimated. The...

Tracing the origin and geographic distribution of an ancestral form of the modern human Y chromosome
Provedor de dados: 97
Autores: BRAVI,CLAUDIO M; BAILLIET,GRACIELA; MARTÍNEZ-MARIGNAC,VERÓNICA L; BIANCHI,NESTOR O.
We screened a total of 841 Y chromosomes representing 36 human populations of wide geographical distribution for the presence of a Y-specific Alu insert (YAP+ chromosomes). The Alu element was found in 77 cases. We tested five biallelic and eight polyallelic markers in 70 out of the 77 YAP+ chromosomes. We could identify the existence of a hierarchical and chronological structuring of ancestral and derived YAP+ lineages giving rise to four haplogroups, 14 subhaplogroups and 60 haplotypes. Moreover, we propose a monophyletic origin for each one of the YAP+ lineages. Out-of-Africa and out_of-Asia models have been suggested to explain the origin and evolution of ancestral and derived YAP+ elements. We analyse the evidence supporting these two hypotheses and...

Autores: Ribeiro,F.C.; Silva,J.C.P.; Santos,J.L.; Pontes,K.C.S.
Avaliou-se a técnica da imunoperoxidase como método auxiliar para a detecção de Mycoplasma hyopneumoniae em suínos naturalmente infectados. Foram colhidos 80 fragmentos de pulmões de 40 animais provenientes de granjas consideradas negativas e 40 de granjas com diagnóstico positivo de pneumonia enzoótica. Com a utilização de soro policlonal específico (IgG de coelho anti- M. hyopneumoniae) observou-se correlação positiva de 77% entre os diagnósticos microscópicos e imunoistoquímicos, enquanto que a correlação entre os diagnósticos macroscópico e imunoistoquímico foi de 49%. Nas granjas consideradas negativas observou-se presença de discreta imunorreação em 22,5% dos casos, o que poderia indicar a existência de reação cruzada com outros microrganismos. Nas...

Argopecten circularis (Sowerby, 1835) fecunddity was estimated during spawnings of February-March 1989 and March-May 1990 in Bahía Concepción, Baja California sur, México. In general, the number of oocytes released during the spawning of Argopecten circularis were potentially related to shell height. The calculated average oocyte wet weight during the maturity period was 8.9033x10ˆ-8 g. Spawning ocurred in individuals 44 to 77 mm in height. The highest fecundity occurred in bivalves 58 to 77 mm in height. Mean fecundity obtained for all heigts by regression analysis during spawning in February-march 1989 was 12, 102, 243 oocytes. In April-May of the same year, there were 17, 917, 006 oocytes, and during March-May 1990, 16, 938, 117 oocytes.

Autores: Mafra,Gabrielle Sousa; Amaral Junior,Antonio Teixeira do; Vivas,Marcelo; Santos,Juliana Saltires dos; Silva,Fernando Higino de Lima e; Guimarães,Amanda Gonçalves; Pena,Guilherme Ferreira.
ABSTRACT The present study resulted from the lack of information on the genotypic expression ruling the resistance to rust and on the main traits of economic importance to the herein addressed crop. The combining ability of 16 popcorn lines and hybrids was assessed in partial diallel cross in two representative locations in Rio de Janeiro State, Brazil, where forty simple hybrids were obtained. The experiments followed a completely randomized block design with four repetitions and were conducted under natural infestation conditions in order to test the southern rust severity in the entire plant (SSW) and in the leaf of the first ear (SFPE), as well as the morpho-agronomic traits of greater interest: grain yield (GY) and popping expansion (PE).

Autores: Rossetto,C. J.; Lourenção,A. L.; Igue,T.; Miranda,M. A. C. De.
O número de vezes que o percevejo-verde Nezara viridula (L., 1758) (Hemiptera: Pentatomidae) se alimentou em cinco diferentes genótipos de soja foi estimado através das bainhas do estilete que permaneceram no local onde ele se alimentou. Foram feitas estimativas a olho nu, através de lupa sem corante e através de lupa após tratamento das vagens com corante de fucsina ácida, como foi proposto por BOWLING. A olho nu, notaram-se distintamente os locais das picadas nos cultivares Paraná e Hill e muito poucas picadas nas linhagens IAC 73/228 e IAC 77/656. A primeira geração do cruzamento entre 'Paraná' e IAC 73/228 apresentou comportamento intermediário, quando observada sem corante. Após tratarem-se as vagens com corante, ficou reduzida a diferenciação entre...

High risk human papillomavirus (HR-HPV) are recognized as a necessary factor to development cervical cancer. During the last decade many studies have found HR-HPV in oral squamous cell carcinoma (OSCC) and normal oral mucosa, however the association between HR-HPV and OSCC is still uncertain. The aim of the study was to determine DNA HR-HPV in normal oral cavity of healthy adults. A cross-sectional study was performed; samples from 77 patients with normal oral cavity were collected at the Dentistry school, Autonomous University of Yucatan, Merida, Yucatan, México. HR-HPV was detected by hybrid capture 2. One sample out of 77(1.2%) was positive for HR-PVH. It was from a man of 50 years old. HR-HPV is present in low rate among healthy oral mucosa. Hybrid...

Provedor de dados: 58
Autores: Blanco,Alina Sánchez; Durive,Osmar Palacios; Pérez,Sulema Batista; Montes,Zoraida Díaz; Guerra,Nelson Pérez.
ABSTRACT The simultaneous production of amylase (AA) and protease (PA) activity by Bacillus subtilis UO-01 in brewery wastes was studied by combining the response surface methodology with the kinetic study of the process. The optimum conditions (T = 36.0 °C and pH = 6.8) for high biomass production (0.92 g/L) were similar to the conditions (T = 36.8 °C and pH = 6.6) for high AA synthesis (9.26 EU/mL). However, the maximum PA level (9.77 EU/mL) was obtained at pH 7.1 and 37.8 °C. Under these conditions, a considerably high reduction (between 69.9 and 77.8%) of the initial chemical oxygen demand of the waste was achieved. In verification experiments under the optimized conditions for production of each enzyme, the AA and PA obtained after 15 h of incubation...

El tema de la descentralización en Ecuador es materia de varios debates, análisis y medidas. La discusión está signada por análisis políticos y jurídicos, y los análisis económicos han sido relativamente limitados. El abordaje económico del tema, por otro lado, es fundamentalmente un asunto de economía política, en tanto incorpora fuertes disputas entre las clases dominantes del país que, entre otros aspectos, tienen que ver con su reproducción económica hoy más restringida y competitiva a escala no solo local, sino nacional y global. De por medio, hay un manejo discursivo que ayuda a construir imaginarios falsos, sobre una reinvindicada descentralización de casi todo y todos.

Autores: Centro Andino de Acción Popular.
La idea de que existe una tradición de pensamiento crítico en América Latina ha sido planteada desde diversas corrientes de interpretación. Es conocida la tradición ensayística que emergió en muchos países de América Latina hasta la primera mitad del Siglo XX como un modo predominante que involucraba análisis, interpretaciones y propuestas que apuntaban a definir temas de identidad y la noción de cultura nacional. Esto se unió con la difusión y recepción del marxismo que sobre todo implicó el predominio de idearios que se tradujeron en un acervo de formulaciones ideológicas y un modo muy acrítico de percibir los regímenes que se implantaron en su nombre. Las ciencias sociales como disciplinas tenían una débil implantación.

Provedor de dados: 122
Autores: Hernández Enríquez, Virgilio.
Durante la década de 1980, coincidiendo con el proceso de transición en América Latina, se  desarrolló un rico debate en torno al régimen que más convenía para el mantenimiento y la profundización de la democracia en la región. Por un lado, se realizaron varios trabajos que centraban su atención en la necesidad de que las nacientes democracias ensayasen formas parlamentarias o con un mayor nivel de consociativismo. Otros trabajos, en cambio, defendieron la vigencia del presidencialismo, sobre todo apelando a razones de orden histórico y a la necesidad de gobiernos con la fortaleza y legitimidad suficientes como para poder llevar adelante los procesos de reforma que simultáneamente empezaban a debatirse en América Latina.

Relecturas de la noción de clientelismo : una forma diversificada de intermediación política y social (Tema central)
Provedor de dados: 122
Autores: Barozet, Emmanuelle.
El clientelismo es una de las formas más conocidas de intermediación política y social; históricamente aparece, en América Latina, aunque no es exclusivo ni único en esta región, como una figura ineludible en la acción política. Innumerables estudios dan cuenta de este fenómeno, y en la línea clásica de éstos, es cuestionado por sus negativas consecuencias para el ejercicio de la democracia. Sin embargo, de los cambios ocurridos en la región, es observable el cómo el clientelismo ha podido adaptarse a las nueves condiciones, con nuevas derivaciones. Por ello es necesario actualizar permanentemente los estudios y conocimientos acerca de este hecho presente en el quehacer político.

El presente trabajo se propone analizar las diferentes razones de la emigración  profesional a través de estudiar el caso de los médicos ecuatorianos que emigraron a Chile. A nivel global las explicaciones mas estudiadas de emigración profesional son “fuga de cerebros”, cambios demográficos y estructurales que han generado la crisis de cuidado en salud, nichos laborales creados por el mercado y creación de redes. Para este trabajo se realizó una investigación cualitativa, mediante revisión documental y entrevistas a profundidad con autoridades académicas de Chile y Ecuador y médicos emigrantes que se encuentran trabajando en el sistema de salud chileno. Los resultados encontrados demuestran que las explicaciones antes anotadas juegan un papel en la...

Un análisis de las negociaciones sobre adaptación en el marco de la COP10 : ¿Sur versus Sur?
Provedor de dados: 122
Autores: Lomónaco Busto, Alana P.
Las categorías Norte y Sur, usualmente utilizadas por la doctrina al referirse al posicionamiento de los estados frente a las problemáticas vinculadas con el cambio climático, son insuficientes para comprender las posturas que adoptaron los países en las negociaciones sobre adaptación y las posiciones que asumieron. Específicamente, en la COP10 los países en desarrollo - o del “Sur” - no mantuvieron una postura unificada frente a los países industrializados- el “Norte” - y, de hecho, se verificaron posiciones divergentes en el seno de la coalición del G77 + China. Esta constatación se opone a la idea de que Sur y Norte operan como ejes cohesionados y/o necesariamente antagónicos. Un factor explicativo del modo en que se conformaron las posiciones entre los...

Paradojas políticas e institucionales del constitucionalismo (Tema central)
Provedor de dados: 122
Autores: Sánchez Parga, José.
Son muchas y muy diversas las democracias actuales, que han recurrido a reformas constitucionales más o menos grandes. Un rasgo común a todas ellas es el reforzamiento de los poderes gobernantes en detrimento de los poderes legislativos y de la representación ciudadana. Tanto la constitución de 1998, en razón de una mayor gobernabilidad, como la nueva constitución de 2008, para garantizar la revolución ciudadana, comparten esta misma orientación. Sin embargo ¿qué eficacia democrática puede tener una Constitución sin instituciones capaces de ponerla en práctica? ¿O son los poderes extraordinarios atribuidos al Ejecutivo, los que pueden compensar la falta de mediaciones institucionales? Que “el poder esté en la Constitución” podría inducir al gobernante a...

La idea de que existe una tradición de pensamiento crítico en América Latina ha sido planteada desde diversas corrientes de interpretación. Es conocida la tradición ensayística que emergió en muchos países de América Latina hasta la primera mitad del Siglo XX como un modo predominante que involucraba análisis, interpretaciones y propuestas que apuntaban a definir temas de identidad y la noción de cultura nacional. Esto se unió con la difusión y recepción del marxismo que sobre todo implicó el predominio de idearios que se tradujeron en un acervo de formulaciones ideológicas y un modo muy acrítico de percibir los regímenes que se implantaron en su nombre. Las ciencias sociales como disciplinas tenían una débil implantación.

Relecturas de la noción de clientelismo : una forma diversificada de intermediación política y social (Tema central)
Provedor de dados: 122
Autores: Barozet, Emmanuelle.
El clientelismo es una de las formas más conocidas de intermediación política y social; históricamente aparece, en América Latina, aunque no es exclusivo ni único en esta región, como una figura ineludible en la acción política. Innumerables estudios dan cuenta de este fenómeno, y en la línea clásica de éstos, es cuestionado por sus negativas consecuencias para el ejercicio de la democracia. Sin embargo, de los cambios ocurridos en la región, es observable el cómo el clientelismo ha podido adaptarse a las nueves condiciones, con nuevas derivaciones. Por ello es necesario actualizar permanentemente los estudios y conocimientos acerca de este hecho presente en el quehacer político.

Autores: Ponce Cevallos, Javier.
El Instituto Latinoamericano de Investigaciones Sociales (ILDIS) y la revista La Tendencia convocaron, para los días 26 y 27 de abril de 2006, a un diálogo entre miembros de diversas organizaciones políticas e intelectuales y algunos investigadores con el fin de ensayar la formulación de una visión del país del futuro. Un ejercicio político, por tanto, entre ciudadanos que miran el país desde el interior de organizaciones políticas y desde el exterior, con posiciones que fueron desde la centro izquierda hasta la izquierda, concebido más allá de la coyuntura electoral —lo que en sí ya obligó a deslindarse de ella— y que, sin dejar de ser realista, intentó vislumbrar algunos sueños.

Se propone una perspectiva que apunta a revelar el modo como se produjo la presencia de Neptalí Bonitfaz en una coyuntura de crisis política a comienzos de los años treinta del siglo pasado. Desde la perspectiva del estilo político de liderazgo, el bonifacismo representó el antecedente y fragua del fenómeno velasquista

Autores: Quintana,Emanuel De La; Mendoza,Alejandro; Cajarville,Cecilia; Bentancur,Oscar; Repetto,José Luis.
ABSTRACT: To study the effect of post-weaning feeding levels on the growth of dairy heifers, 40 animals with 77.7 ± 8.1 days of age and 77.5 ± 9.2kg of body weight were grouped in 10 pens, and each pen was randomly assigned to one of the following treatments for 120 days: feeding level to achieve a body weight gain of 600 (TMEDIUM) or 800 (THIGH) g/day based on a total mixed ration. After this period all heifers were managed as a single group for 150 days. Nutrient intake, behavior, body weight and other morphological measures were recorded in each animal. As a result of the experimental design THIGH heifers had a higher nutrient intake than TMEDIUM heifers, which was reflected in a higher daily weight gain, withers height, heart girth and hip width....

Telenomus remus releasing numbers may vary depending on the crop, plant architecture and/or the plant phenological stage. Thus, we examined the number of parasitoids needed for effective pest control of Spodoptera frugiperda on corn, cotton and soybean. In all crops, the parasitism response in relation to increasing numbers of the parasitoids had a quadratic effect. In corn, the maximum parasitism observed was 99.8% and 96.8% at a parasitoid releasing number of 0.231 and 0.264 T. remus females per S. frugiperda egg at phenological stages V4 and V10, respectively. Differently, in cotton and soybean, the highest parasitim were recorded using the highest tested T. remus releasing numbers (0.297 parasitoid per S. frugiperda egg). In cotton, it was 77.8% and...

В трёх бухтах у г. Севастополя в период 1998 – 2006 гг. оценивали соотношение особей, бывших до вылова «живыми» либо «мёртвыми», в суммарном зоопланктоне. Число «живых» колебалось от года к году в пределах 40 – 77 % в Южной, и 51 – 87 % – в Севастопольской и Круглой бухтах. Доля «живых» была несколько ниже у представителей группы Cladocera, у меропланктона – выше, чем у Copepoda. Количество «живых» особей снижалось у Copepoda на младших стадиях развития и с уменьшением размеров тела у личинок Balanus improvisus, Pleopis polyphemoides, Penilia avirostris. На основании полученных данных оценивалось состояние зоопланктонных сообществ исследованных акваторий. Показаны существенные различия величин численности и биомассы зоопланктона, рассчитанных при...

Growth dynamics of tree species in a remnant of Araucaria Forest
Provedor de dados: 190
Autores: Canetti, Aline; Ruy, Camila Castilla; Mattos, Patricia Povoa de; Braz, Evaldo Muñoz.
Studies that address the appropriate use of forest resources are essential for the management and conservation of forest remnants, such as the Araucaria Forest. Considering the importance to improve the knowledge of the tree species growth in subtropical regions, the present study aimed to assess the intra-annual diameter growth of tree species in Colombo County, Paraná State, Brazil. In November 2009 dendrometer bands were installed in adult trees (15 to 25 trees) of 9 species among the most frequent in the studied Araucaria Forest remnant. The increment in diameter were measured monthly until June 2011. Ocotea bicolor grew faster and more constant than the other species.

Autores: Behling, Alexandre; Sanquetta, Carlos Roberto; Caron, Braulio Otomar; Schimidt, Denise; Elli, Elvis Felipe; Corte, Ana Paula Dalla.
This study aimed to evaluate the content of organic carbon in plant parts (leaves, wood, twigs and bark) of forest species Acacia mearnsii De Wild, Eucalyptus grandis Hill and Mimosa scabrella Benth, under different spacing between trees (2.0 m x 1.0 m, 2.0 m x 1.5 m, 3.0x1.0 m and 3.0 m x 1.5 m), one year after planting. It was also aimed to verify if the conversion factor of 50% can be applied. To determine the organic carbon it was used a carbon analyzer(C-144). The carbon content varied depending on the species, spacing and the part of the plant component used. It was observed that the factors: species, spacing, and parts of the plant are not independent. So, the carbon content measurements should be determined for each species and for each biomass...

Autores: Bernardino, Fernando Salgado; Garcia, Rasmo.
Although researches related to silvopastoral systems have been initiated many years ago in Brazil, there are few informations generated until now. The advantages from a silvopastoral system are inumerous and well recognized. By the fact of being a technique of land using capable of recovering several disturbed ecosystems, the silvopastoral systems by the integration of agricultural, cattle, and silvicultural activities represent a technology that can achieve higher sustainability than the traditional systems as the monocultures. Today, research centers in Brazil dedicate great attention to agrossilvopastoral systems. The government of Minas Gerais State, through the extension offices is promoting the agricultural, cattle and silvicultural practices in an...

Provedor de dados: 195
Autores: Nader, T. T.; Leonel, A. H.; Henrique, C. Y.; Pereira, A. M. S.
A mastite, um processo inflamatório da glândula mamária, é a enfermidade mais prevalente em rebanhos bovinos destinados à produção leiteira, impactando negativamente a economia desse setor (LANGONI et al., 2011). Um rebanho com 15% de ocorrência de mastite bovina pode apresentar 60% de perda de receita bruta (LOPES et al., 2012). Embora a mastite possa ser ocasionada por inúmeros patógenos, bactérias do gênero Staphylococcus spp. têm sido um dos agentes etiológicos mais frequentemente isolados em casos de infecções intramamárias em ruminantes, com destaque para Staphylococcus aureus (DE VLIEGHER et al., 2012). Dentre os diversos fatores de virulência que este gênero apresenta, a capacidade de adesão no epitélio da glândula mamária é considerada um ponto...

Autores: Monteiro, J. E. H.; Matsui, A.; Luzzi, M. C.; Vasconcelos, R. O.
Legal veterinary medicine or forensic veterinary medicine is a specialty recognized by resolution nº 756/2003 of Veterinary Medicine Federal Council, which deals with the application of veterinary medicine knowledge for the purposes of law and justice (ARNS; REIS, 2011). This resolution is not recent, and it has been established in the Brazilian constitution since 1933, describing that in judicial issues involving animals as an exclusive veterinarian function (SABES; GIRARDI; VASCONCELOS, 2016). However, there are few veterinarians working in this field, leaving space to other professionals and leading to a lack of scientific material production (REGO, 2003; MERCK, 2007).

Summer food habits of the Patagonian opossum, Lestodelphys halli (Thomas, 1921), in southern arid Patagonian shrub-steppes
Provedor de dados: 72
Autores: Zapata,Sonia C; Procopio,Diego; Travaini,Alejandro; Rodríguez,Alejandro.
The summer diet of the Patagonian opossum Lestodelphys halli was studied in southern Argentinean Patagonia. Faeces of opossums captured alive and stomach contents from dead animals were collected and analyzed. A wide variety of invertebrates (87.2% frequency of occurrence) followed by birds and reptiles (10.64%) occurred both in faeces and stomachs, and fruits were occasionally consumed. Although the Patagonian opossum was reported as a carnivorous species in captivity, feeding mainly on rodents, reptiles, birds and invertebrates, we did not find remains of rodents in the diet of the opossums. We suggest that Patagonian opossums are not an efficient rodent predator in the wild. The high consumption of invertebrates, reptiles, birds and fruits during the...

Garlic shoot tip culture associated with dry heat thermotherapy (cloves exposed to 37°C for 35 days) were essential for recovering virus free plants of the cv Amarante. In this condition 70% of the explants developed in vitro and produced plants. A total of 77% of those plants was virus free when indexed by ISEM, which resulted in a final index of 54% of virus free plants from treated cloves. The percentage of regeneration decreased to 20% as the temperature increased up to 40°C. However 90% of those plants were virus free, leading to a final index of 18% virus free plants out of treated cloves.

Характеристики микрораспределения Acartia clausi и Oithona minuta и их изменения в онтогенезе
Provedor de dados: 13
Autores: Серегин С. А.; Коршенко А. Н.; Пионтковский С. А.
Рассчитанные для различных онтогенетических стадий Acartia clausi и Oithona minuta из Черного моря величины нормированных дисперсий свидетельствуют о том, что тенденция к агрегированию в онтогенезе в целом возрастает. Наибольшей неоднородностью характеризуется распределение половозрелых самок изученных видов. Размеры однородных по структурным свойствам зон («пятен») для зрелых самок обоих видов равны и составляют около 40 м. В пространстве «пятна» самок A. clausi и О. minuta не совмещаются, о чем свидетельствует анализ взаимных корреляционных функций численности. В пределах исследованных масштабов пространства это может быть связано с различиями локомоторной активности особей.

Морфометрический анализ раковины Cerastoderma glaucum (Mollusca, Bivalvia)
Provedor de dados: 13
Autores: Михайлова Т. В.
Изучено влияние солености на изменчивость размеров и формы раковины черноморской сердцевидки. Выполнено 8 станций в биотопах с разной соленостью. Обработано 400 экз. моллюсков. Средние размеры животных в биотопах с соленостью 17%о выше, чем в биотопах с соленостью 2%о. В процессе роста моллюски сохраняют геометрическое подобие формы раковины. Изменчивость формы раковины шире при понижении солености. При обычной черноморской солености 17%о раковины сердцевидок более вздутые. Индексы формы раковины почти не зависят от возраста и условий обитания и могут быть использованы как видовой признак.

Seven petroleum aggregates (of 30 mm diameter) caught in the East Atlantic region are found to contain 81 specimens of free-living nematodes. 80 of them belong to the Chromadarina cf. laeta (de Man 1876) Mic. 1924 species, one belongs to Camacolaimus sp. Ch. cf. laeta is represented by juvenile and puberal forms (males and females). Detection of considerable number of nematodes shows that inside the petroleum aggregate there exist rather favourable living conditions for eurybiont species. This group of organisms is likely to utilize petroleum aggregates not only as a substrate but is able to actively digest their organic components.

Эколого-морфологические особенности некоторых  водоплавающих птиц  в связи с  полетом и плаванием
Provedor de dados: 13
Autores: Мордвинов, Ю. Е.
На основе морфологического материала по 16 видам водных птиц  (чайкам, пластинчатоклювым, поганкам, гагарам) дается  анализ количественных и качественных особенностей строения крыльев и формы тела в связи с полетом и плаванием. С увеличением экологической связи птиц с водной средой совершенствуются гидродинамические качества  формы тела (показатель),  ухудшаются  летные  свойства  (возрастает нагрузка на крылья), происходит постепенное уменьшение общей длины и  площади крыла за счет редукции дистальной части (первостепенных маховых, кисти), улучшается обтекание тела при плавании в толще воды.  Проксимальный отдел крыла (плечо и предплечье) относительно  увеличивается, что способствует сохранению летных качеств.

Компонентный состав липидоподобных соединений черноморских  донных осадков
Provedor de dados: 13
Autores: Кирюхина, Л. Н.
В дночерпательных пробах донных осадков береговой зоны и материкового склона определен состав липидоподобных соединений. Больше половины в осадках открытого моря составляют полярные липиды,  меньшую часть — малополярные липиды, в том числе 20—30% —углеводороды. В осадках материкового склона преобладают малополярные компоненты (до 60%), представленные в основном углеводородами.      Отличается липидный состав грунтов портовых акваторий, в котором малополярная группировка (до 90% суммы липидов) в основном состоит  из углеводородов. Прослежено, что липидоподобные соединения концентрируются здесь как в органическом веществе, так и в донном осадке.

К вопросу о длительности пребывания под водой и глубине ныряния каланов Enhydra lutris L.
Provedor de dados: 13
Autores: Хромовских, Б. В.; Мордвинов, Ю. Е.
Экспериментами с каланами разного пола и возраста и в результате наблюдений за животными в природе установлены пределы их возможного пребывания под водой и максимальная глубина заныривания. Взрослые звери способны оставаться под водой в течение 8,5—11,5 мин, причем самцы могут находиться несколько дольше самок. Это время является околокритическим для данного вида млекопитающих. С увеличением размеров животных растет и максимально возможное время пребывания их в подводном положении. Предельная глубина, на которую способны нырять каланы в поисках и добывании пищи, составляет около 100 м. Приведенные данные о каланах сравниваются с таковыми для некоторых видов ластоногих. Последние превосходят каланов по этим показателям.

Микрозоопланктон северо-западной части Индийского океана
Provedor de dados: 13
Autores: Павловская Т. В.
Исследованы количественные показатели развития батометрического зоопланктона в период перестройки муссонных течений в северо-западной части Индийского океана. По средним показателям развития микрозоопланктона (2,2.106 экз.м-2 и 2.0 г.м-2) исследуемую акваторию следует отнести к мезотррфным водам. Максимальные его количества были приурочены к областям вихревых циклонических образований, а минимальные — к зонам устойчивого опускания вод. Наибольшие количества организмов обнаружены на глубине 50—75 м над слоем максимальных градиентов плотности. Во всем районе наиболее массовыми из всех рассмотренных групп суммарного зоопланктона являлись ювенальные стадии ракообразных.

Autores: Мордвинов, Ю. Е.
На  основании полученных кинограмм и визуальных наблюдений за плаванием золотоволосых пингвинов в толще воды гидролотка выявлены  механизмы  прямолинейного движения  и маневрирования  в  вертикальной и горизонтальной  плоскостях.  Установлена роль конечностей, хвоста и корпуса  птицы при совершении  поворотов. Получены количественные  показатели динамической устойчивости пингвина  при прямолинейном плавании и маневрах. Тело птицы в обтекающем потоке динамически устойчиво  как в момент  прямолинейного движения,  так  и при  поворотах, причем эти значения для прямолинейного плавания  выше, чем при  совершении маневров. Поворот в вертикальной плоскости осуществляется  более успешно, чем  в горизонтальной.

Влияние высоких концентраций активного хлора на ювенильные  формы балянусов
Provedor de dados: 13
Autores: Шадрина, Л. А.
В настоящее время наиболее эффективным и экономичным способом защиты от морского обрастания является электролизное хлорирование морской воды. При нарушении установленного режима защиты (аварийная ситуация) обрастание, возникшее в циркуляционных системах за этот период, не подавляется после возобновления работы электролизера в прежнем режиме.      Установлено, что активный хлор в диапазоне концентраций 20—250 мг/л может оказывать и угнетающее, и стимулирующее воздействие на ювенильные формы балянусов. Характер воздействия определяется концентрацией реагента, временем контакта и возрастом животного. Механизм угнетающего воздействия активного хлора на ювенильные формы балянусов состоит в нарушении герметичности домика вследствие разрушения краев крышечковых...

Autoregressive models for estimating phylogenetic and environmental effects: Accounting for within-species variations
Provedor de dados: 5
Autores: Cornillon, Pierre-andré; Pontier, Dominique; Rochet, Marie-joelle.
Comparative methods are used to investigate the attributes of present species or higher taxa. Difficulties arise from the phylogenetic heritage: taxa are not independent and neglecting phylogenetic inertia can lead to inaccurate results. Within-species variations in life-history traits are also not negligible, but most comparative methods are not designed to take them into account. Taxa are generally described by a single value for each trait. We have developed a new model which permits the incorporation of both the phylogenetic relationships among populations and within-species variations. This is an extension of classical autoregressive models. This family of models was used to study the effect of fishing on six demographic traits measured on 77...

Identification and characterization of 18 novel polymorphic microsatellite makers derived from expressed sequence tags in the Pacific oyster Crassostrea gigas
Provedor de dados: 5
Autores: Sauvage, Christopher; Boudry, Pierre; Lapegue, Sylvie.
We report the development of 18 new polymorphic microsatellite DNA markers derived from Crassostrea gigas expressed sequences tags. Genotyping of 48 wild adult oysters sampled from Marennes-OlEron bay (France) revealed 12 to 48 alleles per locus. Observed and expected heterozygosity levels ranged from 0.64 to 1 and from 0.77 to 0.97, respectively. The development of these new markers creates a useful complementary tool for population genetics studies, parentage analysis and mapping in Pacific oyster, a species of major aquacultural and ecological importance.

Autores: Alzieu, Claude; Duguy, R.; Babin, Philippe.
Les Mammifères marins, du fait de leur situation en fin de chaîne alimentaire, présentent un intérêt certain pour essayer de déterminer l'état du milieu marin. Il a donc paru intéressant d'étudier la contamination de celui-ci par les micropulluants en utilisant les Cétacés et les Phoques comme détecteurs de pollution. Dans ce but, un programme de recherches a été entrepris grâce aux contrats d'étude proposés par le C.N.E.X.O. de 1977 a 1980 (contrat n° 77/1649), puis en 1981 (contrat n° 81/2448).

The aim of this study was to accurately measure acromial morphology in order to describe the anatomical patterns of its subtypes and to conduct a survey of the literature regarding the relationships between morphological subtypes and their related diseases. We photographed scapulae from the Institute of Anatomy, University Severino Sombra, and analyzed the images using Image-J Software®. The average acromial angle was 139.23° ± 2.781, with no significant difference between the right and left sides. There was a positive correlation between the acromial angle and the angle of the spine of the scapula. The correlation mentioned above plays an important role in disorders of the shoulder-particularly impingement syndrome-which reinforces the importance of...

Autores: Ekinci,C; Tahaoglu,A. E; Yavuz,D; Deveci,E; Aktas,A; Yilmaz,T; Yumusak,Ö; Yükselmis,O.
Propineb is a fungicide with a propylene-bis-dithiocarbamate structure. Pregnant Wistar rats were exposed to 400 ppm propineb concentrations in 5 ml distilled water, 5 days per week until the end of pregnancy. The rats were treated with propineb for 16 days and the brains of litter rats were sacrificed at first day of birth after which their brains were collected. Ultrastructural examination of the brains of the fetuses and propineb-treated pregnant females revealed a variety of histopathological effects. We suggest that mitochondrial damage may be an effective factor for neuron necrosis. These results supported the proposal that the exposure to fungicides such as propineb and to other naturally occurring compounds which inhibit mitochondrial function, may...

Effects of Preweaning Polysensorial Enrichment upon Development of the Parietal Cortical Plate of Undernourished Rats: A Stereological Study
Provedor de dados: 77
Autores: González,Héctor; Adaro,Luis; Hernández,Alejandro; Fernández,Víctor.
This investigation was undertaken in order to quantify the effects of early polysensorial enrichment on the development of cortical pyramids, located in the parietal cortex of rats simultaneously submitted to protein-energy undernutrition. A short period of stimulation during suckling significantly decreases the cellular density in the cortical plate (phylogenetic-ontogenetic evolutionary index). Results suggest that the cerebral cortex develops according to a sophisticated neuronal network, which exhibits a notable degree of structural specificity, regulated by genetic and environmental clues. The most obvious prediction is that environmental influences are probably transduced as a structural expression in the developing parietal cortical plate.

In the left neck side, it was observed that the sternocleidomastoid muscle also had a third part in addition to known sternal and clavicular heads and levator claviculae muscle which arose from the posterior tubercle of the transverse process of the 3rd cervical vertebra and attached to the posterior margin of the clavicle. An awareness of this variations may be important because of its close relationship with neurovascular structures during neck operations.

Provedor de dados: 77
Autores: Suazo Galdames,Iván; Zavando,Daniela.
In this study we tested the hypothesis that diagnostic performance of the morphological indicators for sexual dimorphism are reduced as they are applied in skull and mandibles of older subjects. We used 275 adult human skulls, 250 of these with mandible, all subjects with sex and age registry. Sixteen classic morphological indicators of sexual dimorphism were evaluated, this information was compared with the registry and results noted in terms of precision. The best general performance of morphological indicators of sexual dimorphism were recorded in the 31 - 40 and 61 - 70 years, age range groups. Lowest precision ws recorded in the group corresponding to subjects between 21 ­ 30 years. Our results do not support the proposed hypothesis and suggest a...

El quiste broncogénico es un remanente del desarrollo de traquea y bronquios. Alteraciones en la migración de células durante el desarrollo, permite que estos grupos originen quistes revestidos por epitelio respiratorio. La ubicación más habitual es la intratoráxica, dentro de ella, la intrapulmonar es la más frecuente, seguida de la mediastínica. El diagnóstico definitivo se establece mediante la biopsia diferida. Es una patología poco frecuente y las presentaciones extra torácicas son muy infrecuentes, por lo que compartimos dos casos, uno de ubicación sublingual y otro de ubicación subcutánea en zona escapular.

Teratogenic Effect of Ethylene Glycol-Methyl Cellosolve Mixture in Rats.: I. Reproductive Damage
Provedor de dados: 77
Autores: Arteaga-Martínez,Manuel; García-Peláez,Isabel; Aguirre-Luna,Oswaldo M; Saavedra-Ontiveros,Dolores.
We investigated the reproductive damage and teratogenic effect of an ethylene glycol-methyl cellosolve mixture on gestating Wistar rats, which received a daily intraperitoneal dose of different concentration of the mixture on day 8 of gestation until day 20. In rats treated with the mixture the number of live fetuses decreased and reabsorptions increased with increasing concentrations of the mixture, as well as the number of abnormal fetuses. We conclude that the ethylene glycol-methyl cellosolve mixture possesses a higher teratogenic potential than each of its constituents separately, producing reproductive damage, external fetal abnormalities, growth delay, and increased fetal death.

Variations in The Vascular Supply of Pancreas and Transverse Colon: A Case Report
Provedor de dados: 77
Autores: Silva Júnior,L. M; Alexandre,M; Gonçalves,L; Silva,F. S; Caetano,A. G.
During anatomical dissection of the abdominal cavity of an adult male corpse, a changing pattern of vascular supply of pancreas and of the transverse colon was observed. The inferior pancreatic artery and the middle colic artery arose from a common trunk of the superior mesenteric artery. Moreover, the lienal artery did not direct a dorsal branch to the neck of the pancreas, but rather sent two greater pancreatic arteries (proximal and distal) to the body of the gland and one caudal artery to the terminal portion of the pancreas. We also observed a large communicating branch between the proximal portion of the middle colic artery and the ascending branch of the left colic artery, previously described as artery of Moskowitz. Based on these data, clinical...

The authors have used non-laying and laying hens (Lohmann Brown), in order to study morphological aspects development of tunica mucosa of the oviduct. The results showed that the oviduct of the hen is well-developed at the left side, atrophied at the right side and consists of five different regions: infundibulum, magnum, isthmus, shell-gland and excretory section (vagina). During 1-120 days in oviduct is the most advanced caudal part, where height and width folds of a tunica mucosa is more than in cranial part, that probably, is caused with the future function of these departments. In the period oviposition (150-540 days), the tunica mucosa is most advanced in such departments, as: magnum, isthmus, shell-gland

Characterization of the Uterus and Mammary Glands of the Female African Giant Rats (Cricetomys gambianus, Waterhouse) in Nigeria
Provedor de dados: 77
Autores: Akinloye,Adebayo Koyuum; Oke,Bankole Olusiji.
Morphology of the uterus and mammary glands were studied in sexually matured female African giant rat. The uterus was identified as being duplex, having two separate uterine horns and two cervices. The two cervices were partially fused and separated by a mid-saggital septum. Their thick musculatures projected caudally into the vagina as the portio vaginalis uteri. The results also showed that eight mammary glands, distributed along the lateral aspects of thoracic and inguinal regions, were present. The thoracic and the inguinal regions had four mammary glands each and were arranged in two pairs of cranial and caudal rows. These findings fill some gaps created by the dearth of information on the reproductive biology of the female African giant rat.

Variant Inferior Root of Ansa Cervicalis
Provedor de dados: 77
Autores: Babu,B. Prakash.
Ansa cervicalis is a loop of nerves found in the anterior wall of the carotid sheath in the carotid triangle of neck innervating infrahyoid muscles. Its superior root has fibres from the first cervical nerve that leaves the hypoglossal nerve and joins the inferior root formed by the branches from the second and third cervical nerves. The two roots join to form ansa cervicalis. The ansa cervicalis nerve formation is relatively complex, as its course and location along the great vessels of the neck vary. In the present case on the left side of an adult male cadaver the inferior root was absent and the contributions from C2 and C3 were joining independently with the superior root of ansa to form ansa cervicalis. However no such variation was found in the ansa...

Preservation of Haemal Nodes Fixed by Means of Two Different Aldehyde Fixatives: a Scanning Electron Microscopic Study
Provedor de dados: 77
Autores: Guerrero,F; Cerutti,P; Marcaccini,A.
Glutaraldehyde is the fixative most commonly used in electron microscope studies of biological tissues, however it is often necessary to use samples which were not fixed in this fixative, even with the usual uncertainty of the results that may be obtained. The fixation is the more delicate step of the sample processing. Therefore in this work, the quality of preservation of haemal nodes fixed with two classic aldehyde fixatives: formaldehyde and glutaraldehyde we have compared under the scanning electron microscope. Our results showed that both fixatives were successful in preserving the morphology of haemal nodes components; however glutaraldehyde conferred satisfactory results mainly in the preservation of parenchymal cells, whereas formaldehyde was...

Diabetes is now considered one of the main threats to human health in the 21st century and many researchers are dedicated to investigate the physiopathology of the disease, with further insights on the managements of its major complications. Since understanding the pathophysiology of the major complications of diabetes and their underlying processes is mandatory, experimental models of the disease may be useful as they allow the recognition of the early mechanisms involved in the long-term complications of diabetes. Peripheral nerve involvement is highly frequent in diabetes mellitus and it has been documented that one third of diabetic patients have peripheral neuropathy. The true prevalence is not known and reports vary from 10% to 90% in diabetic...

Provedor de dados: 77
Autores: Shetty,Surekha D; Nayak,Satheesha B; Kumar,Naveen; Somayaji,S. N; Rao,Mohandas K. G.
Occurrence of variant muscular slips from pectoralis major muscle is rare. In this report, we present a rare case of aberrant muscular slip associated with the pectoralis major muscle which we call costodorsalis. This muscular slip originated from the 6th rib near the costochondral junction and ran along the lower border of pectoralis major muscle. It crossed the axilla from medial to lateral side and merged with the latissimus dorsi muscle. This type of origin and insertion is unique and has not been reported earlier. The knowledge of this muscle variation may be of special importance to the anesthesiologists, physiotherapists and plastic surgeons.

Provedor de dados: 77
Autores: Fayed,Masoud Hassan; Elnasharty,Mohamed; Shoaib,Mahmoud.
The stomach of three species of non-human primates was investigated by lectin histochemistry to clarify the staining affinity and distribution patterns of their sugar residues. All gastric regions, with little differences between the deep and superficial parts of the same region, were rich in. in N-acetylglucosamine and/or neuraminic acid. Although, the superficial regions of the gastric mucosa were scanty in N-acetylgalactosamine, a- D-glucose and a -D-mannose, the deep parts of the gastric mucosa were rich in these sugars. In conclusion, there is a difference among the mucosubstances of surface and foveolar mucous cells, mucous neck cells, and gastric gland cells. This indicates heterogeneous composition of gastric mucus, or mucus molecules with...

Autores: Macéa,José Rafael; Fregnani,José Humberto Tavares Guerreiro.
For adequate treatment of patients with breast cancer, mastologists should have a complete understanding of the anatomy of the thoracic wall, axilla and breast. However, the classical anatomical descriptions in textbooks make it difficult to gain full mastery of this subject, because the books usually deal with its elements separately. In an endeavor to resolve this difficulty, the present authors have conducted an extensive review, to describe the muscles, blood vessels and nerves of the thoracic wall and in the axilla that are of interest to mastologists. The axilla was described in detail, with emphasis on its limits, walls and contents, and highlighting the lymph nodes in this region.

Autores: Rai,Rajalakshmi; Ranade,Anu V; Prabhu,Latha V; Prakash,; Rajanigandha,V; Nayak,Soubhagya R.
Presence of additional muscles in the pectoral region has often been reported. We report about the presence of Pectoralis Minimus muscle, in a male cadaver. It was present deep to the pectoralis major muscle and superomedial to the pectoralis minor muscle. The variant was closely related to the branches of thoracoacromial vessels where one of the branches was passing between the pectoralis minor muscle and the variant muscle. Hyperabduction of the arm may compress these vessels giving rise to certain vascular symptoms. Also these variations should be borne in mind during certain surgical procedures in the pectoral region.

Autores: Flores Quintana,C; Blanco Cohene,T; Arbués,R; Domitrovic,H; González,J.
Durante el período reproductivo, en el ovario de los teleósteos se forman cíclicamente folículos primarios, los que maduran y son liberados en el momento de la ovulación. Sin embargo, algunos de ellos desarrollan un proceso de atresia con degeneración y reabsorción, el que para ser considerado un evento fisiológico debería predominar al final del ciclo reproductivo. Las características morfológicas de ovarios de Prochilodus lineatus fueron analizadas para identificar la presencia de folículos atrésicos como indicadores de posibles modificaciones de su biología reproductiva que afecte la repoblación de la especie. En los ovarios de P. lineatus predominaron los cambios morfológicos que se corresponden con la denominada atresia tipo I, y los folículos...

An unusual unilateral variation in the branching pattern of axillary artery was observed in a 60 year oíd female embalmed cadáver. The axillary artery had only two branches arising from its proximal (first) part and no branches from its remaining distal (second &amp;amp; third) parts. The branches are superior thoracic (usual) and another large collateral (unusual) branch. This collateral branch is the origin of several important arteries as the circumflex scapular, thoracodorsal, posterior circumflex humeral, thoraco-acromial and lateral thoracic arteries. We propose to ñame this artery as common subscapular trunk. The course of this collateral artery (common subscapular trunk) and its branches and also clinical significance of this variation are...

La Piel y sus estructuras asociadas permiten a los seres vivos subsistir en los diferentes ambientes ecológicos. El desarrollo de la piel y sus anexos en diferentes especies repite patrones comunes. De suma importancia es la interacción epitelio-mesénquima como regulador inicial de este desarrollo. El evento crucial en la formación de anexos, es la aparición de una placoda ectodérmica, a la cual se le asocia una condensación de células dérmicas, expresándose proteínas como Sonic Hedgehog (SHH) y la proteína morfogenética del hueso (BMP) para luego dar forma al anexo de cada especie. En esta revisión describiremos las etapas sucesivas que transcurren en la formación de la dermis, epidermis y anexos, con énfasis en las proteínas que dirigen el proceso.

The neural plasticity showing the ability of nervous system to change its structure and function is a well-documented fact. However regional variation within a CNS structure to undergo plastic changes has been shown by limited studies. Along medial-lateral sequences of parasagittal sections, the molecular layer thickness of primary fissure borderlands in rat cerebellar left hemisphere was studied to assess the regional difference in plasticibility. Despite the homogeneity of cerebellar histology, this study showed that there is a significant interlobular difference between ML thicknesses of Prf borderlands. In addition, it revealed that the thickness alters in a significant trend within each borderland. The quantitative heterogeneity of cerebellar...

However, oligodontia is a severe type of tooth agenesis involving six or more congenitally missing teeth, excluding the third molars. Oligodontia has a low prevalence and is a very rare condition. The aim was to show this case report of a 13-year-old female patient who presented oligodontia with absence of eight permanent teeth and condylar atrophy on left side. The patient had no history of any syndrome or systemic disease according to the anamnesis. Is very important to know oligodontia features to perform a carefully treatment plan.

Autores: Cortés-Delgado,Natalia; Pérez-Torres,Jairo; Hoyos,Julio Mario.
Transparency technique to demonstrate cartilage and skeleton has been used from years 70. This consists basically of the muscle digestion through an enzyme (trypsine), and the staining of cartilage and skeleton using alcian blue and alizarin red on specimens previously fixed to formalin. This technique can be used to study the state of the cartilage and the bones in different stages of the development and to observe abnormalitys. Also it can be used to demonstrate museum specimen skeleton preserved in liquid. In this article is showed the application of this technique for the first time in rodents and adult bats, besides some annotations to optimize the procedure.

Clinical and Functional Significance of Accessory Brachialis Muscle: An Unique Anatomical Variant
Provedor de dados: 77
Autores: Sirisinagandla,Sreenivasa Rao; Potu,Bhagath Kumar.
A thorough knowledge of the variations in the patterns of muscle insertion and the consequent neurovascular entrapment due to them is important for orthopedic and plastic surgeons. During routine dissection, we encountered a unique occurrence of an accessory brachialis muscle (acBr) blending with the medial aspect of bicipital aponeurosis in the cubital fossa. It also entrapped the median nerve and brachial artery due to its superficial position. The abnormality reported here might result in neurovascular compression symptoms in the upper limb and possible mechanical advantages or disadvantage in the flexion of elbow joint. To the best of our knowledge, the brachialis variant insertion we present here is rare in the list of its anomalies. We also discuss...

Autores: Coriolano,M. G. W. S; Lins,O. G; Amorim,M. J. A. A. L; Amorim,A. A. Jr.
The anconeus is a small muscle situated at the elbow. Although the anconeus is active during elbow extension its importance for the movement is probably small. It could work as an elbow stabilizer. The object of this study was to investigate some anatomic and architectural characteristics of the anconeus, in the hope of shedding light on its function. We studied twenty adult cadaveric specimens. The anconeus originates by the lateral epicondyle of the humerus and inserts along the proximal ulna. The superficial shape of the anconeus is triangular. Tridimensionally the anconeus resembles a hemisected rectangular-based pyramid, with the base at the ulna and apex at the lateral epicondyle. The muscle fibers arise obliquely from the tendinous expansion and...

Autores: Oluyemi,Kayode A; Okwuonu,Uche C; Baxter,D. Grillo; Oyesola,Tolulope, O.
Effects of graded dosages of methanolic extract of Aspilia Africana were examined on the estrous cycle, uterine weights and histology to determine its effects on the reproductive functions of 25 cyclic female rats. The rats were randomized into five groups A, B, C, D, and E. They were given Omg/kg body weight, 150 mg/kg body weight, 200 mg/kg body weight, 250 mg/kg body weight, and 300 mg/kg body weight, respectively. The effect on the estrous cycle was determined by vaginal lavage while routine histological preparations were done with haematoxylin-eosin stains. All values were statistically compared at appropriate confidence intervals. Estrous cycles were significantly reduced in a dose-dependent manner and histology revealed a dose-dependent toxicity

Provedor de dados: 77
Autores: Wang,Jia-xiang; Li,Peng; Zhang,Xiao-ting; Ye,Li-xun.
Ghrelin, an endogenous ligand for the growth hormone secretagogue receptor, has been detected in the thymus of multiple vertebrates. However, little is known about its distribution in the thymus of the African ostrich. In this study, we evaluated the distribution and morphological characteristics of ghrelin-producing cells in the thymus of the African ostrich. Our results revealed that the thymus consists of a capsule and a parenchyma, which comprises the cortex and medulla. Compared to the cortex, the medulla had a fewer number of thymocytes and a greater number of epithelial cells. Additionally, three thymic corpuscles were identified. Ghrelin-immunopositive (ghrelin-ip) cells were detected both in the cortex and medulla of the African ostrich thymus,...

Fractal Dimension of Dog Kidney Proximal Convoluted Tubuli Sections by Mean Box-Counting Algorithm
Provedor de dados: 77
Autores: Gil,Julio; Gimeno,Miguel; Laborda,Jesús; Nuviala,Javier.
The possibility of characterizing the proximal convoluted tubuli of the dog kidney by means of a unique and objective value, is an attractive idea in order to automate its recognition in anatomy and patology. For this, we obtained a fractal dimension of the proximal convoluted tubuli in the dog kidney by mean box-counting method. The fractal value we obtained is a flat dimension, and it is different than the line fractal dimension of the dog kidney arterial pattern, which was previously calculated by us (Gil et al., 2006). Thus, from optical microscopy images, we are able to obtain a single quantitative measure to discriminate these dog kidney components. This measures can use to automate its recognition. Fractal geometry provides many advantages when...

Provedor de dados: 77
Autores: Acer,Niyazi; Usanmaz,Mustafa; Tugay,Urnut; Erteki'n,Tolga.
It is natural that there is close relationship between cranial capacity, and the size of brain. Several studies have estimated the cranial capacity which indirectly reflects the brain volume. This study was carried out on 366 (226 male and 140 female) healthy university students aged between 17-26 years old at Mugla University, Mugla, Turkey. By using linear dimensions of the head the mean cranial capacity and SD in males and females were 1411.64+118.9 cm³ and 1306.95+162.9 cm³, respectively. There was a significant difference between genders (p&lt;0.05). This investigation was showed the cranial capacity is larger in males than females. We also proposed a regression formula that could be used to predict the cranial capacity

Autores: Zhu,Lei; Wang,Jun Jie; Shi,Xiao Dong; Hu,Jiang; Chen,Jian Gang.
The stomachs of the yellow-billed grosbeaks were examined by means of light microscopy. The mucous membrane of the proventriculus presented many folds and sulci. The sulci were lined by simple columnar cells with basal nuclei and clear acidophilic cytoplasm. The proventriculus glands were constituted by many round or elliptical glandular lobules. The sulci and the collecting duct of compound tubular glands showed an intense positive reaction in PAS and AB stain. The gizzard was characterized by an internal abrasion-resistant lining cuticle and a thick muscular layer. The cuticle, gizzard glands and muscular layer in two sides were thicker than those in the cranial and caudal.

Autores: Lalwani,Rekha; Rana,Kum Kum; Das,Srijit; Khan,Riyazul Qamar.
The external jugular vein, which traverses the sternocleidomastoid muscle superficially, is known to exhibit variations in its formation and course. There are less reports on the communication of the external and internal jugular vein. During routine cadaveric dissection, we detected an abnormal communication of the external jugular vein and the internal jugular vein, in a 45 year male cadaver. The knowledge of both normal and abnormal anatomy of the superficial veins of the neck may be important for clinicians performing catheterization and surgeons operating in the region of the neck. The presence of such anomalous communications may also be important for radiologists performing angiographic and sonographic studies

The morphology and relative size of the tympanic bulla of three species of dasypodids from Argentina, Chaetophractus villosus, C. vellerosus and Zaedyus pichiy, were studied. The bulla was observed to be morphologically similar and evidently hypertrophied in the three species. The degree of hypertrophy was higher in C. vellerosus and C. villosus than in Z pichiy. By means of ANCOVA it was clear that, although C. villosus has a bigger skull than C. vellerosus, the relative size of their tympanic cavity was similar in both species. On the other hand, the skull of C. vellerosus and Z pichiy are of similar size but the bulla was relatively shorter in the later

Morphometry is a non-invasive method important to assess the size, proportions, and composition of the human body. Because the prediction is an important subject in almost all life sciences, the aim of this research was to find out the cephalofacial variables that may predict the body height. Three cephalofacial variables and the body height were measured on 288 adult male subjects of the Kosovo Albanian population, aged 18­35 years old. Using the procedures of regressive analysis we found that cephalofacial variables: head height, head circumferences, face height, significantly may predict body height, and in this way we derived the specific regression equation for estimation of the body height, based on these cephalofacial variables. The predicted body...

Uno de los endulzantes más comúnmente utilizado es la fructosa. La fructosa es directamente metabolizada en el hígado y se puede transformar en glucosa, posteriormente es almacenada como glicógeno constituyéndose en una fuente de energía para los hepatocitos. Todo el exceso de fructosa se convierte en lípidos ejerciendo un efecto tóxico sobre el hígado, similar al producido por el exceso de alcohol, pudiendo provocar hígado graso no alcohólico (NAFLD). El objetivo de esta revisión es reunir hallazgos recientes en relación al efecto de la ingesta de fructosa en altas concentraciones y su relación con el NAFLD.

Currently there is a growing concern, in both population and governments, to identify the effects of substances commonly disposed of into rivers and lakes, on aquatic fauna and flora. Thus the objective of the present study was to verify effects of biodegradable detergents and water from an urban lake on gills and liver of two neotropical fish species of great economic importance, Astyanax altiparanae and Prochilodus lineatus. In order to do so, lipofuscin, also called the ageing pigment, was used as bioindicator. After one and five months of experiment both tissues accumulated this pigment. These data are discussed from physiological points of view, related with lipid peroxidation and mitochondrial damage.

This document is a description of the macroscopic functional anatomy of the ulna bony prominences in the White-footed Tamarin (Saguinus leucopus), a neotropical endemic, and monotypic primate of Colombia. Few studies have been conducted on its anatomy, and thus its ulnar morphology, an essential element for this animal's quadrupedal arboreal locomotion, remains unknown. This study is based on eight specimens, fixed in formalin at 10 % whose ulnas were extracted in order to describe the main bony prominences along with muscular and ligamentous fixation functions. These elements of the locomotor apparatus and the multiple anatomical contours of the ulna of the White-footed Tamarin, exhibit characteristics for positional and articular adjustment with other...

Posterior Slope of Tibial Plateau in Adult Nigerian Subjects
Provedor de dados: 77
Autores: Didia,Blessing C; Jaja,Blessing N. R.
Normal values of the tibial slope are necessary for realignment of displaced fractures of the tibia crest, repair of cruciate ligaments and correction of knee deformities. True lateral radiographs of normal knees were obtained in 119 males and 93 female Nigerian subjects. The tibial slope was then measured according to the anterior tibial cortex method. Mean angle in sampled subjects was 12.3 ± 4.90 (range: 0-240). Sex differences were statistically insignificant (p&gt;0.05). This study provides reference values of tibial slope among indigenous adult Nigerians. It also highlights on the clinical relevance of the angle and the need to establish normal ranges in other African populations.

Provedor de dados: 77
Autores: Singh,Royana; Jaiswal,Amit; Shamal,S. N; Singh,S. P.
During routine dissection of a 42 year old male Indian cadaver posterior abdominal wall, variations in the testicular vessels were observed. The right testicular artery arose from the right accessory renal artery, which originated from the ventral aspect of the abdominal aorta. The left testicular artery originated from the ventral aspect of the aorta in almost the same horizontal line as the right accessory renal artery, just below the superior mesenteric artery and 1.79 cm, above the origin of the renal arteries. The right vein drained into the right accessory renal vein instead of the inferior vena cava, while the left testicular vein drained into the left renal vein. The presence of variation of both the testicular arteries as well as the testicular...

Los Orígenes de la Sociedad de Anatomía Normal y Patológica de Chile
Provedor de dados: 77
Autores: Rodríguez Torres,Alberto; Cárdenas Valenzuela,Julio.
Desde los inicios, anatomistas y patólogos se unen en el año 1938 creando la Sociedad de Anatomía Normal y Patológica, con el fin de estimular sus investigaciones, buscar relacionarse tempranamente con morfólogos del resto de América y potenciar sus publicaciones en los Archivos Chilenos de Morfología. Es así como morfólogos chilenos provenientes de las principales Universidades del país participan por primera vez en Congresos y Jornadas tanto nacionales como internacionales. Quizás el trabajo en común con los cadáveres fue un punto fundamental en sus inicios, más el avance de los conocimientos en cada una de estas disciplinas y diferencias políticas posteriores serían dos hechos que explicarían que se separasen posteriormente en el año 1970. Sería por...

Compared Morphology of the Cephalic Musculature in Five Species of Genus Urotrygon (Chondrichthyes: Urolophidae)
Provedor de dados: 77
Autores: González Isáis,Mónica; Montes Domínguez,Héctor Marcos.
This work aims to describe the morphology of dorsal and ventral cephalic musculature in five species of genus Urotrygon. Muscular differences were observed, mainly in the development level. Muscles showing certain degree of variation in the dorsal region were the cucullaris and the ethmoideo-parethmoidalis. In ventral view, higher variation was observed. Muscles showing differences were the depressor rostri, the depressor hyomandibularis, the preorbitalis medial, the coracohioideus, and the depressor mandibularis. Urotrygon aspidurus was the species with the largest differences, as it has no mandibular depressor, and the rostral depressor is quite developed. The shape and arrangement of cephalic musculature in Urotrygon is similar to that reported for...

Course Pattern of the Muscular Branch of the Median Nerve in Sri Lankans Hand
Provedor de dados: 77
Autores: Senanayake,Kithsiri J; Salgado,Sujatha; Fernando,Ranil.
Transligamentous variant of the recurrent motor branch is having a higher risk of getting damage during both endoscopic and open carpal tunnel releases. The incidence of the transligamentous variant is about 7% to 80% world wide. This wide variation of the incidence could be due to the failure of identification of the distal edge of the flexor retinaculum from the obliquely oriented fascia that runs from the distal edge. We used two criteria to identify the distal edge; the abrupt change in the thickness of the flexor retinaculum and its colour change in cross section. The incidence of transligamentous variant is rare and the reported high incidence could be due to an error in identification of the distal edge of the flexor retinaculum as shown by Kosin...

A Case of Unusual Anatomy: Maxillary Central Incisor with Two Root Canals
Provedor de dados: 77
Autores: Rodrigues,Evaldo Almeida; Silva,Sílvio José Albergaria da.
Success in root canal treatment is achieved after thorough cleaning and shaping followed by complete obturation of the canal system. Therefore, endodontic therapy requires specific and complete knowledge of the internal and external dental anatomy, and its variations in presentation. Such treatment may be performed in root canal systems that do not comply with the normal anatomical features described in standard textbooks. The internal anatomy of the maxillary central incisor is well known and usually presents one root canal system. This case report describes an endodontic retreatment of a maxillary central incisor with two canal systems.

Variations in the branches of the abdominal aorta were determined during a routine abdominal region dissection of a 70-year-old male cadaver. Left gastric artery arose as the first root from antero-lateral of aorta. Coeliacomesenteric trunk occurred as a thick root. After 29.9mm, coeliacomesenteric trunk bifurcated as coeliac trunk and superior mesenteric artery. Coeliac trunk bifurcated as splenic artery and common hepatic artery. These multiple variations which change the normal anatomic structure of the abdominal aorta have to be kept in mind by surgeons, radiologists and anatomists.

Autores: Yeri,Luis Andrés; Houghton,Eduardo Javier; Palmieri,Bruno; Flores,María; Gergely,Marcelo; Gómez,Jorge E.
The cephalic vein shows a scarce description, especially in the deltopectoral triangle, and its ending in the axillary vein. Some established considerations such as "superficial vein, located in the deltopectoral groove, accompanied by braches of the thoraco-acromial artery, which ends in the deltopectoral triangle in the shape of fan arch" should be reevaluated. Procedures difficulties in the la catheterization deserve for a more accurate description. A descriptive, prospective study is performed. The goal is to determine the anatomy of the cephalic vein in the deltopectoral triangle, with a special focus on the characteristics concerning its path and type of termination. Findings show that the cephalic vein is deeply placed and has a different path than...

Lymphatic Drainage of the Breast: from Theory to Surgical Practice
Provedor de dados: 77
Autores: Fregnani,José Humberto Tavares Guerreiro; Macéa,José Rafael.
Until recently, complete removal of axillary lymph nodes was performed as part of the treatment of breast cancer. Sentinel lymph node biopsy (SLNB) in selected cases has reduced the number of cases of wide axillary dissection and the related morbidity. Knowledge of breast lymphatic drainage is essential for understanding the principles behind SLNB and also for performing safe and correct axillary lymphonodectomy. This paper describes in detail the anatomical issues relating to breast lymphatic drainage and the correlated axillary and extra-axillary lymph nodes. In addition, it shows the application of this theoretical knowledge to surgical practice, especially with regard to SLNB and lymphonodectomy. The surgical nomenclature is compared with the current...

Autores: Rojas,Mariana; Signore,Iskra A; Mejías,Roberto.
Durante el desarrollo embrionario, las células de muchos tejidos se diferencian de acuerdo con la información de posición que se establece por las gradientes de concentración de morfógenos. Estas son moléculas de señalización secretadas en una región restringida de un tejido y se difunden lejos de su fuente para formar una gradiente de concentración. La molécula de un mismo morfógeno actúa generalmente en distintas etapas de desarrollo de un organismo y puede provocar reacciones muy diferentes en las células en función de su historia de diferenciación. Los morfógenos más conocidos son miembros del factor de crecimiento beta (TGF-b), Hedgehog (Hh), familias Wnt y los microRNAs.

Evidence of Fractality in a Pattern of Crystallization of Bovine Cervical Mucus Obtained at Oestrus
Provedor de dados: 77
Autores: Cortés,Manuel E; Hauyón,Roberto; González,Fernando; Vigil,Pilar.
Fractality has emerged as a feature of the organization of some complex natural systems. Several biological secretions show fractal-like patterns for their crystallization phenomena but their presence in crystallizations of bovine cervical mucus (BCM) is yet unknown. In order to assess the fractality of BCM crystallization, samples of this fluid were taken from heifers at oestrus, their crystalline patterns photographed and its morphology analyzed. Among the many images obtained for BCM crystallizations, one of them had a highly symmetrical geometric arrangement, possessing three zones characterized by pine-like, arboriform structures, evidencing a remarkable similarity between them. Moreover, fractal dimensions obtained for these zones were statistically...

Anomalous Lobar Pattern of Right Lung: A Case Report
Provedor de dados: 77
Autores: Modgil,Vishal; Das,Srijit; Suri,Rajesh.
The right lung classically has two fissures, an oblique and a horizontal, dividing it into three lobes namely the superior, middle and lower. The anomaly of the lobar pattern has been described by many research workers on CT scans, where as, there are fewer studies on gross anatomical specimens. In the present case , which was incidentally detected, we report three fissures dividing the right lung into four lobes. Such abnormal fissures and lobes are clinically important for identifying broncho-pulmonary segments. Anatomical knowledge of anomalies of fissures and lobes of lungs may be important for surgeons performing lobectomies, radiologists interpreting X ray and CT scans and also of academic interest to all medical personnel

The aim of this study was to evaluate the stability and harmony of the morphostructural format of the Marin Magellan Meat Merino breed in order to contribute to knowledge about the differentiation of sheep populations. In summer 2010, evaluation on a sheep population coming from an incomplete absorbent crossbreeding of Corriedale by Australian Merino breeds was done in Magallanes Region, Chile. All three and five year-old ewes (62 and 50, respectively) were measured. Fourteen body measurements were taken and nine body indexes were calculated. Results show that the evaluated sheep population does not show significant intergenerational differences in most of the morphostructural variables. At the same time, there is a high between-age similarity in the...

Autores: Araújo,Eduardo José de Almeida; Hermes,Catchia; Miranda Neto,Marcílio Hubner de; Almeida,Elton Carlos de; Sant'Ana,Débora de Mello Gonçales.
Effects of protein and B-complex vitamin deficiency were assessed with respect to the morphometry of myenteric neurons in the descending colon of adult rats. Sixteen animals were divided into two groups: Control Group (CG, n=8) and Experimental Group (EG, n=8). The CG received 22% protein chow and the EG received 4% protein chow for 120 days. The descending colon was submitted to NADH- and NADPH-diaphorase technique in order to evidence nervous cells in the whole mounts preparations. In the EG, NADH-d positive neurons presented reduced nuclei, while NADPH-d positive neurons showed atrophy of the soma area (~41.7%) inducing an increase of the proportion occupied by the nucleus inside in the soma of these cells.

Back to the Debate: Sternalis Muscle
Provedor de dados: 77
Autores: Hung,Laurie Y; Lucaciu,Octavian C; Wong,Jessica J.
The sternalis muscle (SM) is an anatomical variant found in the anterior thoracic wall. While the attachment sites of SM are generally agreed upon, the innervation and function of this muscle are not well established. Cadaveric and surgical explorations to date report that SM is innervated by either the pectoral nerves or the anterior branches of the intercostal nerves, or a combination of both. Knowledge of SM is relevant to health care providers specialising in imaging and/or surgery of the anterior thoracic wall. This paper aims to raise awareness in the medical community of the clinical relevance of SM through two case reports and a brief literature review.

Absence of Musculocutaneous Nerve Associated with Variations of Distribution Patterns of the Median Nerve
Provedor de dados: 77
Autores: Zhang,Yong; Yang,Shengbo; Yang,Fangjiu; Xie,Peng.
Variations in the brachial plexus and the distribution patterns of its branches are not uncommon. A communicating branch, which is the most frequent variation, often arises from musculocutaneous nerve to median nerve. However, the branches arising from lateral cord of the brachial plexus and median nerve instead of musculocutaneous nerve are very rare. Detailed description of the abnormalities is important for surgical procedures. Our case study reports the musculocutaneous nerve was absent, a branch from the medial cord innervated the coracobrachialis muscle and two branches from the median nerve innervated the biceps and brachialis muscles, respectively. Moreover, the median nerve gave off the lateral antebrachial cutaneous nerve. This report provides...

Spodoptera frugiperda is a polyphagous insect that causes economic losses to several crops in Brazil and is the major obstacle to corn production. Researches focusing on alternative control, e.g. botanical products are expanding to offer a wide variety of molecules that interfere with different biological parameters of insect pests. Thus, this study tested the hypothesis that clove essential oil affects the spermatogenesis, ovarioles histochemistry and the fertility of S. frugiperda. The results showed that clove essential oil affects the gametogenesis of S. frugiperda ovarioles, reflecting negatively on its reproduction, proving to be a promising tool for controlling this pest.

Autores: Afshar,Mohammad; Golalipour,Mohammad Jafar.
The latissimus dorsi muscle is a flat and triangular muscle that covers the lumbar region and the inferior part of thorax. This muscle supplied by thoracodorsal nerve(C6, C7,C8), a branch of posterior cord of brachial plexus. Many reports showed that a muscular axillary arch , flat muscle arising from lateral border of latissimus dorsi , may be seen in 7% of the population, but there is little information about the innervation of this part. This report deals with dissecting the axillary region of a 41 year-old male cadaver in which we observed a muscular axillary arch was innervated by a single nerve branch of pectoral loop

Autores: Murlimanju,B. V; Prabhu,Latha V; Pai,Mangala M; Ganeshkumar,C; Sarvepalli,Ankamma.
A lumbosacral transitional vertebra is a rare congenital anomaly which occurs because of defect in the segmentation of the lumbosacral spine during development. During routine osteology classes for the medical students at the Kasturba Medical College, Mangalore, India, one of the sacra showed the fusion of the fifth lumbar vertebra with the sacrum. The specimen showed an incomplete fusion (sacralization) on the left side and the transverse process was of the large butterfly shape, while on the right it was about the usual size. Though this variation is well known, the details of this anomaly are rarely reported in the anatomical literature. Since there is a strong relationship between the lumbosacral transitional vertebrae and low back pain, this anomaly...

La osificación es un proceso que ocurre durante la embriogénesis al iniciar el periodo fetal. Se caracteriza por una condensación de células mesenquimáticas con una bipotencialidad condro y osteogénica para formar tejido óseo mediante osificación endocondral y membranosa respectivamente. La regeneración ósea es la respuesta generada con el fin conseguir la restitución del tejido tras un trauma. Este evento se caracteriza por la formación de un callo perióstico secundario cuya ontogénesis sigue los patrones embrionarios al presentar ambos tipos de osificación, además de la regulación molecular propia durante la etapa fetal, concluyendo que ambos procesos están íntimamente relacionados durante la ontogenia del individuo, con la excepción del proceso...

La dimensión vertical es una medida aproximada de las relaciones fisiológicas intermaxilares. Su obtención es un proceso sensible y metódico que produce efectos craneofaciales colaterales cuando es erróneamente lograda. Los conceptos individualistas de su obtención deben ser cambiados e interiorizados de una manera colectiva debido a la complejidad de la dinámica masticatoria que exige una perspectiva más amplia de esta noción. La correspondencia entre la dimensión vertical y lo funcional-disfuncional cráneo-cervical es innegable y va mas allá de una relación exclusivamente dental.

Provedor de dados: 77
Autores: Alibardi,Lorenzo.
The present ultrastructural study on developing and regenerating feathers of chick and zebrafinch describes the ultrastructural changes that occur during the differentiation of barb cells that leads to the formation of the ramus of barbs. Differently from barbule and barb cortical cells that accumulate feather keratin, barb medullary cells undergo to lipid degeneration. Eventually, lipids disappear and medullary cells become empty cavities in the central part of the ramus. In barb medullary cells feather keratin is accumulated in few peripheral bundles that merge with those of cortical cells to fom the wall of the ramus. The latter is joined with branching barbules. The process that controls the transition from keratin-synthesizing to lipid-producing barb...

An Unusual Termination of Seven Veins in the Jugulo-Subclavian Junction
Provedor de dados: 77
Autores: Panagouli,Eleni; Tsaraklis,Athanasios; Gazouli,Ioanna; Venieratos,Dionyssios.
During anatomical dissection of a female Caucasian cadaver in our department, we observed an unusual termination of seven veins at the jugulo-subclavian junction. Normally, the jugulo-subclavian junction is formed by the union of the internal jugular vein and the subclavian vein, and gives rise to the brachionocephalic vein. In our case, except from these two, five additional veins, namely the cephalic vein, the transverse cervical vein, the external jugular vein, the anterior jugular vein, and the vertebral vein, were also joined at the level of the jugulo-subclavian junction, in order to form the brachionocephalic vein. Such a variation has not yet been reported in the literature.

The abdominal aorta of the rabbit has been in the focus of research to develop new platforms of training diagnostic and therapeutic protocols; and for testing endovascular devices and materials, however, few descriptions of the anatomy of the abdominal aorta and its emerging visceral branches has been reported on the scientific literature for this specie. Anatomical variations are common and should have in mind during research and clinical trials. The aim of this study was to describe the different patterns that can occur in the visceral branches arising from the abdominal aorta in the rabbit.

Autores: Pompei Filho,Horácio; Guimarães,Antonio Sergio; Suazo Galdames,Iván Claudio.
The lateral pterygoid muscle (LPM) is important in the physiology and dysfunction of the temporomandibular joint (TMJ), which has described the presence of a third head in the lateral pterygoid muscle (THLPM). The purpose of this study was to evaluate the prevalence of THLPM and its relationship with the TMJ disc through magnetic resonance imaging (MRI). It was evaluated 178 MRI of the TMJ of healthy individuals, in images that presented THLPM, and these were defined and measured at the surface inserted into the disc. The prevalence of THLPM was 20.22% (n = 36). Insertion of THLPM was made entirely on the TMJ disc, the average area of insertion was 4.14mm (SD 1.35) in women and 4.67 (SD 2.68) in men, but these differences were not significant. We concluded...

Medial Patellofemoral Muscle: Report of a Rare Variant
Provedor de dados: 77
Autores: Beddings Moreno,Ignacio; Burdiles Orellana,Álvaro; Contreras Olea,Oscar.
Muscle anatomic variants range from absence of a muscle to supernumerary muscles, with a spectrum of possibilities that include anomalous course, anomalous origin or insertion, accessory slips, and others. The most common muscle variants around the knee include aberrant origin and accessory slips of the gastrocnemius muscles, presence of tensor fascia suralis muscle, and accessory popliteus. The medial patellofemoral ligament is a distinct extra-articular condensation of fibers located superficially to the medial joint capsule. We describe the presence of an accessory medial patellofemoral muscle in the expected location of the medial patellofemoral ligament, which to our knowledge has not been described in the literature before.

Autores: Xie,Zhaohui; Li,Jingting; Cheng,Pu.
The dorsal surface of the tongue gustatory organs of Chinese fire-bellied newt (Cynops orientalis) was observed by employing the light and scanning electron microscopy (SEM) techniques. The results revealed that the rostral and median part of the tongue presents a round apex and covered by taste disks (TDs). They are usually roundish or ellipsoidal in shape and are 20-35 mm in diameter. The many openings of the lingual glands are 4-8 mm in diameter exist in the lateral border or median part of lingual body. The gustatory organs on the tongue did not differed form those presented in other species in Caudates. These may indicate the functions of gustatory organs on the tongue related to their life habit.

El objetivo de esta investigación fue ofrecer datos morfométricos de las estructuras óseas involucradas en la técnica quirúrgica de colocación de implantes cigomáticos, proveyendo así, informaciones que faciliten la planificación y realización de dicho procedimiento. Considerando los valores promedios obtenidos en nuestro estudio, concluimos que el mayor espesor del hueso cigomático se encuentra en la zona media del hueso. Sugerimos que el anclaje superior del implante cigomático no debe extenderse hasta el margen posterosuperior del hueso cigomático, ya que el espesor del hueso a este nivel no ofrece condiciones de adecuada oseointegración de implantes.

Autores: Ottone,Nicolás Ernesto; Prum,Natalia; Dominguez,Mario; Blasi,Esteban; Medan,Carlos; Shinzato,Sergio; Finkelstein,Diana; Bertone,Vicente Hugo.
The classic description of the hand's superficial palmar arch is based on the anastomosis among the ulnar and radiopalmar arteries, a branch of the radial artery. However, the arch formation is highly variable regarding the size of the arteries that make it up and due to the existence of branches coming from other arteries and adding up as tributary to it. The objective of this paper is to classify these possible varieties, to define the formation of the arch, the reasons for its variable arrangement and the importance of its clinical and surgical applications. 86 formalized hands were dissected at 40%. There is prevalence concerning the size of the ulnar artery, with or without an arch. The anatomic knowledge of the variability in the arch formation...

Gingival Metastasis from a Testicular Choriocarcinoma: An Unusual Case Report and Review of the Literature
Provedor de dados: 77
Autores: Velasco,Ignacio; Aguilar,Leonardo; Pastrian,Juan; Mebus,Cristina; Martínez,Benjamín.
Metastasic tumours to the oral cavity are extremely rare lesions that represent 1% of all oral and maxillofacial malignancies. Most reported cases involve the jaw bones than the soft tissues. Metastasis to the oral soft tissues most prevalently affects the gingiva and alveolar mucosa. Gingival metastasis may have an unremarkable clinical appearance and they can be difficult to distinguish from more common hyperplasic or reactive lesions that appear to be benign entities, such as peripheral giant-cell granuloma, pyogenic granuloma and peripheral ossifying fibroma. We present an unusual case of a testicular choriocarcinoma metastasized to the maxillary gingiva mimicking a reactive lesion. In addition, we also present a literature review of previous reported...

Double Plantaris Muscle: A Cadaveric Study with Clinical Importance
Provedor de dados: 77
Autores: Rana,Kum Kum; Das,Srijit; Verma,Ranjana.
The gastrocnemius, plantaris and the soleus muscles, comprise the posterior (flexor) compartment muscles of the leg. The plantaris muscle is responsible for causing plantar flexion of the foot. The muscle is vestigial in human beings and has much clinical importance. The muscle is known to exhibit variations but there are few reports on the existence of double plantaris muscle. The present case report describes double plantaris on both sides of a cadaver, which was detected during routine dissection. Knowledge of both normal and abnormal anatomy of the plantaris muscle is important for surgeons performing tendon transfer operations and clinicians diagnosing muscle tears

Brachial plexus shows several variations in its formation and branching pattern. Variations in the formation of the trunks are very rare. We studied 44 dissected specimens specifically for variations in the formation of the trunks of the brachial plexus. 5 cadavers (11.3%) showed variations in the formation of the trunks. All the variations were unilateral. In one cadaver (2.27%), the middle trunk was formed by union of C7 and C8 roots and lower trunk was formed by T1 root. Upper and middle trunks were fused with each other in one specimen (2.27%). In 3 specimen (6.81%), the C5 root pierced scalenus anterior before joining C6 to form the upper trunk. Knowledge of its variations is of importance to orthopedic surgeons, neurologists and anesthesiologists.

Central nervous system of reptiles has the ability to grow and regenerate during adult life of the animal. Therefore, cells creating CNS of this animal class should compound substances or molecules enabling neuroregeneration. Cells directly involved in this process have not been clearly characterized, especially in cell culture environment. Morphology of reptilian glial adherent cells should be known better to find any differences from mammalian CNS cells. We isolated glial cells from olfactory bulb and cerebrum from gecko (Eublepharis macularius) and cultured separately. We have observed populations of cells with proliferative capacity in both types of cultures. Also, we have detected lipid molecules deposits within their cytoplasm, which localization was...

Provedor de dados: 77
Autores: Basso,Ana Paula; Sidorkewicj,Nora Silvia; Casanave,Emma Beatriz.
Two methods of measurement of bullar dimensions (callipers and scaling from digital images) and subsequent application of four volume formulae (rectangular prism, cylinder, ellipse and elliptical cone) were tested to find the most appropriate non-destructive method for estimating the bullar volume in Chaetophractus villosus. Material for the study consisted in clean adult skull (n=22). Real volume was obtained from latex casts of the tympanic bulla. Each estimation was corrected by a factor based on the differences between the estimated and the real volumes. Highest accuracy (5-7 % of underestimation) and precision (coefficient of variation: 13.27 %) were obtained from callipers and application of rectangular prism, cylinder and ellipse formulae. The...

Autores: Seema,; Verma,Poonam.
Cephalic index (CI) and head shape are greatly affected by geographical, sex, age and racial factors. Such data is of great medico legal and forensic importance which indicates that cephalic index can be used as marker of ethnicity. There is less published literature about cephalic index of Punjab population. Hence, we undertook this study to document the cephalometric characteristics and gender differences in cephalic index of Punjabi community. Head length, head breadth and CI were determined for 500 medical students (17­23 years) of Punjab. The mean cephalic index for males was 80.52 and for females 84.32 which was statistically significant. On comparison with the existing literature the Punjabi community can be categorized as Brachycephalic/...

Provedor de dados: 77
Autores: Schimming,Bruno Cesar.
The cervical salivary glands of the armadillo Dasypus novemcinctus was examined by light microscopy. These glands are situated on either side of the neck, divide in lobes and show a presence of a salivary bladder, associated with the main ducts of the gland. This gland is histologically a typical mixed glands, containing both mucous and serous elements, with mucous acini as the predominant secretory unit. The bladder itself is composed of a wall made up of pseudostratified epithelium, skeletal muscle and connective tissue. In general, the morphology of the cervical salivary glands appears similar to that described in other species of the mammals.

Observation of sexual chromatin has shown to be very helpful in gender forensic diagnosis. In the present study we analyzed the diagnosis performance of the method in, non-treated or treated with conventional bone techniques, exhumed bone pieces. We used long bones of male and female individuals, the method applied is described in Suazo et al. (2010). In the non-treated exhumed pieces, the general accuracy of the method was 75%, while in the treated pieces the method was inapplicable due to the lack of cells in the tissue. Our results suggest that it is possible to determine the sex of aged human bones buried under different conditions through a fast and simple histological method, but the treatment with physical and chemical means eliminates the remaining...

Autores: Fuentes,Ramón; Issa,João Paulo Mardegan; Iyomasa,Mamie Mizusaki; Oporto,Gonzalo; Prieto,Ruth; Borie,Eduardo.
Autogenous bone grafts are considered to be the gold standard in bone regeneration because of their osteogenic activity; however, due to limited availability of intraoral donor sites and the need to resolve the demands of patients requires an alternative to these. Two male patients were submitted to implant surgery in two stages with 6 months intervals between each of them: the first was exodontia and placement of DBM graft into the socket; the second stage was the drill with a 2 mm internal diameter trephine in center of the alveolar ridge previously grafted with DBM and subsequent implant placement. The samples were analyzed under histological techniques. A very mature bone was observed at 6 months after DBM graft placement in the sockets, showing it to...

Casseri fue un brillante anatomista y docente de la Universidad de Padua, cuya vida se vio ensombrecida por la eterna rivalidad con su mentor Fabrizio. Tras su muerte, la historia también le dio la espalda, y un cúmulo de hechos desafortunados ha ido otorgando a su discípulo Spiegel la credibilidad de buena parte de sus logros. A pesar de aportar un legado anatómico incuestionable, todavía hoy es el gran olvidado en muchos textos de la especialidad. Como tributo a su obra nosotros proponemos denominar a las hernias de la línea semilunar como Hernias de Spiegel-Casseri.

Autores: Sareen,Deepika; Agarwal,A. K.; Kaul,J. M.; Sethi,Ashwani.
For radical surgery of the past, the precise definition of the clefts of the paranasal sinuses was of limited significance. In the recent years, the transsphenoidal approach to the pituitary gland has come into practice and the study of the surgical anatomy and relationships of the sphenoid sinus has gained increased significance. To better define this anatomy, 20 sphenoid sinuses in cadavers were dissected to reveal important anatomical relationships, dimensions, volume and pneumatization of the sphenoid sinus. The results of the study are discussed with particular reference to the important surgical anatomical features of the sphenoid sinus. The results also point towards the possibility of racial variations in terms of relationships of the sphenoid...

Supernumerary nostril is a very rare congenital anomaly, which includes additional nostril with or without accessory cartilage. In the present case of the left supernumerary nostril, a small cavity of around 3 mm diameter and accessory lower lateral cartilage were present. The cavity was lined with mucous membrane and filled with mucoid discharge .Nasal endoscopy of accessory nasal cavity revealed that it was small as compared to normal nasal cavity and did not communicate with the ipsilateral nasal cavity. The diameter of the normal anterior nasal opening was less on left side as compared to right side. Unilateral supernumerary nostril may occur because of the Assuring of the lateral nasal process during fetal growth.

One of the rare but clinically important variations is the origin of deep circumflex iliac and inferior epigastric arteries from it instead of from external iliac artery. We report here the origin of inferior epigastric and deep circumflex iliac arteries from the femoral artery bilaterally. Both the arteries passed up deep to the inguinal ligament and had a normal course and distribution after crossing the inguinal ligament. Knowledge of these variations is of importance in plastic surgery, anterior approach to the hip joint, draining psoas abscess or reducing a femoral hernia.

Autores: Silva-Junior,Geraldo de Oliveira; Miranda,Sandro Wilson da Silva; Mandarim-de-Lacerda,Carlos Alberto.
The formation of the coronary vasculature is a fundamental event in heart development and involves a series of carefully regulated temporal events that include vasculogenesis and angiogenesis. This review focuses the knowledge concerning the formation of the coronary arteries available so far and some molecular mechanisms involved in this process. Understanding coronary embryogenesis is important for interventions regarding adult cardiovascular diseases as well as those necessary to correct heart congenital defects. The insight of the coronary artery development as a result of ingrowth changed the understanding of several congenital coronary artery variations and anomalies described in gross anatomy.

The Dual Role of Senescence in Tumorigenesis
Provedor de dados: 77
Autores: Chuaire-Noack,Lilian; Sánchez-Corredor,Magda Carolina; Ramírez-Clavijo,Sandra Rocío.
Senescence was rendered a tumor suppressor mechanism based on the observation of its protective effect against cancer in young organisms under conditions of oncogene activation or inactivation of tumor suppressor genes. In addition to this beneficial effect, senescence has been deemed to have age-associated deleterious effects because, apparently, senescence not only recapitulates aging and therefore loss of function and tissue regeneration capacity, but can also induce preneoplastic changes in adjacent stromal cells, provoke degenerative diseases or induce the production of tumor cell growth promoting factors. For that reason, senescence has become an attractive therapeutic target against cancer. This paper reviews some of the latest findings on the role...

Aggressive Pregnancy Tumor (Pyogenic Granuloma) with Extensive Alveolar Bone Loss Mimicking a Malignant Tumor: Case Report and Review of Literature
Provedor de dados: 77
Autores: Martins-Filho,Paulo Ricardo Saquete; Piva,Marta Rabello; da Silva,Luiz Carlos Ferreira; Reinheimer,Daniele Machado; Santos,Thiago de Santana.
Oral pyogenic granuloma is a hyperplastic inflammatory lesion commonly associated to local irritation or trauma. Females are more affected than men probably due to the vascular effects of hormones that occur during puberty, pregnancy and menopause. In the pregnancy, the lesions are known as "pregnancy tumor" and tend to occur more frequently during the second and third trimester. In the oral cavity, histopathological examination is required for diagnosis, since the lesion is clinically indistinguishable from other reactive lesions and, usually, there is no evidence of bone involvement. The authors report a rare case of pyogenic granuloma with destruction of alveolar bone mimicking a malignant tumor in a 20-year-old woman in the 19th week of pregnancy.

Autores: Ajayi,Nasirudeen Oladipupo; Lazarus,Lelika; Satyapal,Kapil Sewsaran.
During routine dissection of the upper limbs of a Caucasian male cadaver, multiple variations of the branches of the brachial plexus were observed. On the left side, the musculocutaneous nerve was absent and the muscles of the anterior compartment of the arm were innervated by the median nerve. The median nerve was also formed from three roots viz; two from the lateral and one from the medial cord of the brachial plexus. On the right side, the musculocutaneous nerve contributed a long communicating branch to the median nerve in the distal half of the arm. There were also communicating branches between the ulnar and radial nerves in both limbs at the humeral level. The co-existence of these variations appears to be unique and has not been reported in the...

Liver samples of Oreochromis niloticus cultivated in floating net cages were fixed for histological and ultrastructural studies with the objective of describing the hepatic parenchymal structure and the intrahepatic exocrine pancreatic tissue. Anatomically, the liver showed only two hepatic lobes. Histological analysis demonstrated that the hepatocytes were spread out as anastomotic cords, arranged in two cellular layers and surrounded by sinusoids. The intrahepatic exocrine pancreatic tissue exhibited an acinar arrangement and was diffused in the hepatic parenchyma. Structural analysis showed that the hepatocytes had a rounded nucleus and a rough endoplasmic reticulum with a parallel disposition to the nuclear membrane. The exocrine pancreatic cells...

Any compression of testicular arteries may lead to loss of spermatogenesis and gonadal hormone production, existence of the variational arteries is accountable in cases of vasoligation, orchidopexy and other surgical approach on them. Anomalies of the testicular blood arteries were observed during dissection of the pelvic cavity in a 68-year-old male cadaver. This report describes a very rare case of lack of testicular arteries. For the blood supply to the testis, thick deferential arteries form some vascular winding and loops and course accompanied by deferent duct to the testis. This case report would serve as ray of light for knowledge of the possible variations of the testicular arteries during surgical procedures.

The frontal sinuses can provide significant evidence for forensic identification. The peculiarity of the frontal sinus contours allows a precise and meticulous analysis, reducing the risk of errors on the part of the forensic experts. To describe the use of cone-beam computed tomography as an alternative to obtaining images of the frontal sinuses. In addition, it is proposed the adoption of some anatomic references to do the axial slicing, which should have its plan being tangent to the upper limit of the orbital cavities, as well as the sagittal slicing, which should be done under the midline, so that all sinus boundaries would be observed while error margin in obtaining comparative images would be reduced.

Anomalies arising in the embryological development of the aortic arch and its branches are essencial in the emergence of variations in the origin and course of supra aortic vessels. Classically, 95% of cases, the aortic arch gives rise to the brachiocephalic artery, left common carotid artery and left subclavian artery. While the left vertebral artery arises normally from the left subclavian artery. In this presentation we describe two cases of the left vertebral artery being born of the aortic arch. The importance of anatomical knowledge of this arterial variety is fundamental for base neck and aortic arch surgery, in cervicothoracic trauma that compromises the vascular elements and in endovascular procedures in the region.

In experimental studies the outcome variable is measured at initial time, usually called "baseline", and then in several times called "follow-up" measurement(s). The study question of interest in an experimental study is whether there is a significant difference effect between treatment and comparison group, after intervention. In addition, one wants to estimate the difference effect between groups. This paper studies some of the strategies, including a simulation process, that one can be used for analyzing data coming from an experimental study as above, and considers using or not using the baseline measurements. Three parametric and two non-parametric strategies are evaluated considering only one follow-up measurement. The baseline measurement is...

Autores: Nayak B,Satheesha.
An abnormal artery arising from external iliac artery was found during routine dissection class for medical undergraduates. The artery took its origin from the external iliac artery midway between its origin from common iliac and termination as femoral artery. The abnormal artery divided into two branches; an ascending and a descending. The ascending branch supplied iliacus and iliac crest. The descending branch entered the femoral triangle by passing behind the femoral sheath. It supplied the muscles of femoral triangle and anastomosed with medial circumflex femoral artery. The knowledge of this variation may be of use for surgeons doing surgery of femoral hernia.

In medical sciences, any experimental animal model should be reproducible and adequate to the purpose of simulated human physiological response. In bone injury response research, when bone substitutes are in use, it is of primary importance that studied defects fail to heal unless treated with the tissue engineering therapy under study. This failure defines the concept of "critical size defect" (CSD) wich has different limits according to the animal species used and the location of the defect. Although this is a basic concept, when the aim of the study is to investigate the interface Bone-Biomaterial, it is of primary importance to obtain as much contact area as possible. In order to do so, we propose a modified surgical approach to the classical...

Autores: Meruane,Manuel; Smok,Carolina; Rojas,Mariana.
The embryonic development of the facial area, neck, nasal, oral and pharyngeal cavities with glands, involves growth and fusion of multi-dimensional processes. There is involvement of elements from the embryo-derived local 3 layers cells further neural crest derived cells from the neighbors rhombomeres. The neural crest cells are involved in the formation of local skeleton, among other structures. The study of evolution from jawless vertebrates shows us how Hox genes are expressed in different species, and how this determines the formation of different structures. The following review contemplate some morphological, molecular and evolutionary basis of facial and neck development, with emphasis on mammals with an epilogue concerning to the face and neck...

Human Oscicular Chain Articulations: Asymmetric Sound Transmission
Provedor de dados: 77
Autores: Ramirez Aristeguieta,Luis Miguel; Ballesteros Acuña,Luis Ernesto.
The mechanism for conducting acoustic energy via middle ear oscicles is still a controversial topic and will remain so until consensus is reached regarding whether it amplifies or reduces sound transmission. 22 paired human temporal bone blocks and 1 left block were studied. Digital measurements were taken of the tympanic membrane, oscicular articulations and the oval window; the results were then correlated. A relationship of non-lineal areas was found amongst the structures being studied, suggesting a sound transmission relationship combining both sound reduction and amplification. A complex relationship of levers could be observed originating in an oscicular and articular asymmetric relationship suggesting an amplifying function in initial sound...

Autores: Singh,Rajani.
Body segments exhibit consistent ratios with stature, age, gender and race. Thus prediction of stature from cranial remains is vital in establishing the identity of an unknown individual in natural calamities and archaeological exploration where entire body skeleton is not available. Little is known about the cranial dimensions in Indian population. Hence the study was carried out to predict stature, age and sex for solving medico-legal problems, anthropological complexities and archaeological investigations. Undergraduate students in the age group of 17-26 years of CSM Medical University, UP, India were selected as subjects because of easy access. Cranial dimensions of the subjects were measured by spreading calliper and Todd' head spanner. Heights of...

Provedor de dados: 77
Autores: Freire,Alexandre Rodrigues; Rossi,Ana Cláudia; de Oliveira,Viviane Cristina Souza; Prado,Felippe Bevilacqua; Caria,Paulo Henrique Ferreira; Botacin,Paulo Roberto.
The recognition of emissary foramens is important not only for understanding the regional neurovascular anatomy, but also to distinguish normal from potentially abnormal structures. Thus, the aim of this study was to review the literature on anatomical and clinical aspects of the mastoid, parietal and sphenoid emissary foramens. It was found that the emissary foramen presents importance in clinical practice because it acts as a route of spread of extracranial infection to the intracranial structures and also possible complications in neurosurgery, due to its influence in the performance of techniques such as radiofrequency rhizotomy for treatment of trigeminal neuralgia. The anatomical knowledge of the emissary foramens is important due to variability in...

Provedor de dados: 77
Autores: Ajadi,A. Temitope; Antia,E. Richard; Akang,E. Effiong.
A three- year- old Doberman was presented with complaint of lethargy and weight- loss. Physical examination revealed a mass in the right abdomen. Laboratory abnormalities included anaemia, azotaemia and metabolic acidosis. Sonogram of the mass was an anaechoic area surrounded by hypoechoic tissue. The mass was located between the right kidney and ovary and showed papillary and tubular pattern of cystadenocarcinoma. Nephroureterectomy and ovariohysterectomy was performed; however bitch was euthanized owing to poor improvement, while necropsy of the left kidney revealed an end-stage kidney. It was concluded that the cystadenocarcinoma must have arisen secondary to a primary ovarian adenocarcinoma through stromal invasion.

The dorsum of the tongue of Dasypus hybridus (Desmarest, 1804) studied by scanning electron microscopy, shows conical and branched filiform, fungiform and vallate papillae. No foliate papillae were seen. Conical filiform papillae are placed in the apex of the tongue and posterior to the vallated ones. Branched papillae are compactly distributed over the entire dorsal surface of the tongue. Fungiform papillae are more abundant on the first third of the tongue and they are distributed between filiform papillae. Only two vallate papillae were observed placed in the posterior third of the tongue, surrounded by a deep grove. The presence of taste buds on fungiform and vallate papillae indicate that both are involved in the sense of taste, while the filiform...

Provedor de dados: 77
Autores: Torre,F; Erthal,R; Fernandes,R. M. P; Babinski,M. A; Cisne,R.
The Kaplan´s anastomosis represents the communication between the dorsal and superficial branch of the ulnar nerve distal to ulnar canal. In the present study, a case about this nerve communication, found in a male adult cadaver, is reported. Information about brachial plexus distal anastomosis is fundamental for interpretation of clinical and electrophysiological findings, in order to establish the precise diagnosis of neurological lesions at this level. Its relations with flexor carpi ulnaris muscle's tendon and with pisiform bone exposes it to iatrogenic lesions during surgery.

Provedor de dados: 77
Autores: Segovia,Y.
La apoptosis o muerte celular programada es un proceso que ocurre durante el desarrollo del sistema nervioso. El objetivo de este estudio fue observar los patrones de apoptosis que se producen durante el desarrollo embrionario de la retina, desde el estadio S16 al momento del nacimiento, mediante miscoscopía óptica y electrónica. Se utilizaron retinas de embriones de tortuga. Nuestros datos muestran que los primeros signos de apoptosis comienzan en el estadio S16, en la capa nuclear interna y alcanzan su máxima densidad tanto en la capa nuclear interna como en la capa de células ganglionares en S20, para extinguirse, prácticamente, en el momento del nacimiento. Por otra parte, la apoptosis sigue un gradiente centro-periferia.

Morphological Diversity of the Ovaries of the Mexican Teleost Fishes
Provedor de dados: 77
Autores: Kobelkowsky,Abraham.
The morphological diversity of the ovaries from a total of 90 species of teleosts in the Mexican fauna was analyzed. Ovaries were classified according to the following characters: their number, symmetry, fusion grade, trajectory, cross section, and topographical location. The fusion of both left and right ovaries was the character showing most diversity, mainly in the Cyprinodontiformes and its tendency to the viviparity. However, the most notably character was the extravisceral development of the ovaries in the Pleuronectiformes, implying the forward orientation of the gonoduct and the forward position of the female genital opening. The urogenital system of a typical perciform, Bairdiella chrysoura is proposed as a morphological pattern of the Teleostei.

The gastro-omental artery is one of the branches of the common hepatic artery. Alterations in the embryonic development of the ventral splanchnic arteries can cause marked variations. A rare variant of the right gastro-omental artery was observed during dissection of a 50-year-old male cadaver. The occurrence of this variant has not been reported in the specialized literature. This case of a different origin of the gastro-omental artery is described in detail in order to provide information that may contribute to upper abdominal surgeries.

Autores: McMullen,Roger L; Chen,Susan; Moore,David J.
Utilizando una técnica de fluorescencia, registramos mapas de los fluoróforos presentes en varios tipos de tejidos queratinosos. Descubrimos que la fluorescencia de todas las muestras analizadas tienen rasgos en común. Observamos el aminoácido triptófano en todos los tejidos. Asimismo, nos parece que la máxima principal es debido a las kinureninas que son productos metabólicos y degradativos del triptófano. Esta máxima constituye un conglomerado de varias moléculas como L-kinurenina, 3-hidroxikinurenina y N-formilkinurenina. La proporción de kinureninas que tiene el triptófano depende del tipo de tejido y del grado de pigmentación. También, la longitud de onda de excitación y emisión depende de estos parámetros.

The caudal skeleton is one of the most important tools to evaluate teleostean interrelationships, but just the anatomy of few species have been investigated. Black-striped pipefish (Syngnathus abaster) has never been examined for its caudal morphology. Here, red alizaryn is applied as specific staining for calcified structures, providing a better understanding of caudal skeleton organization. Our results and interpretation just partially fit with previous knowledge on other Syngnathus species. This emphasizes both the importance of facing same problems with new technics and methodologies, and the existence of a heterogeneous situation between close-related taxa

Las células germinales primordiales (CGP) son los precursores de los ovocitos y espermatocitos. Se caracterizan por ser las únicas capaces de retener verdaderamente la capacidad de desarrollo pluripotencial luego de la gastrulación. Estas células provienen del epiblasto, diferenciándose del resto de las células somáticas gracias a señales emitidas por el ectodermo extraembrionario y endodermo visceral tempranamente a partir de los días 6,0 a 7,5 dpc. en la especie murina. Luego migran a través de intestino primitivo y mesenterio dorsal hasta llegar a las crestas genitales alrededor de los 10,5 dpc. Las células germinales primordiales tienen una variada morfología y expresión génica, por lo tanto presentan distintos marcadores según el estadío en el que se...

Autores: Codón,Stella Maris; Estecondo,Silvia; Casanave,Emma Beatriz.
The histology of the salivary glands of the armadillo Dasypus hybridus (Desmarest, 1804), was studied. Two pairs of salivary glands, parotid and submaxillary, and a salivary bladder are distinguished. Parotids are located anteriorly to the submaxillary glands. They are purely serous glands and excretory intralobular ducts, intercalated and particularly striated ones, are very numerous. Submaxillary glands are of greater size. They possess two lobes, which differs in their histology and histochemistry. The anterior lobe is mixed and the presence of numerous intralobular excretory ducts is remarkable. The bigger posterior lobe is mucous. Intralobular excretory ducts are observed, but they are not as abundant as in the anterior portion

Autores: Igiri,Oyono; Ekong,Moses Bassey; Egemba,Geoffrey Okechukwu; Asuquo,Olaitan Ruth.
This study was to ascertain the pattern of arrangements and distributions of the superior mesenteric artery (SMA) in a Nigerian population. Seventy-five cadavers certified as Nigerians were obtained from the dissecting room of the Department of Anatomy, University of Calabar after ethical approval from the Institution's Ethics Committee. Their abdomens and their contents were excise to expose the vessels. Based on the pattern of arrangements of the SMA, the cadavers were grouped into three (A, B, and C). Group A had 45 cadavers and this constituted 60% which were similar to the commonly documented patterns. Groups B and C had 20 and 10 cadavers respectively constituting 26.7% and 13.3% pattern of arrangement, some of which have not been documented before....

Autores: Kwinter,David M; Lagrew,James P; Kretzer,Julie; Lawrence,Cara; Malik,Diksha; Mater,Megan; Brueckner,Jennifer K.
The occurrence of a unilateral second plantaris muscle was discovered during the anatomical dissection of a 47 year old female with Huntington Chorea Disease. The cadaver was found to possess bilateral plantaris muscles and a distinct anomalous muscle morphologically resembling a second plantaris on the medial right leg. The inner and outer bellies of the anomalous plantaris arose proximally from the medial condyle of the femur and formed a short tendon that fused distally with the tendon of the lateral plantaris muscle.

Provedor de dados: 77
Autores: Prakash,Babu B; Bhagath,Kumar Potu.
During routine dissection of head and neck, an unusual drainage in pattern of the veins on the left side of the face was observed in an adult male cadaver. In the present case, he superficial temporal vein united with maxillary vein to form retromandibular vein within the substance of the left parotid gland. The anterior division of retromandibular vein joined with facial vein to form common facial vein that drained into left subclavian vein directly. Knowledge of such variations is important for surgeons performing head and neck surgeries. Facial veins are often grafted into carotid endarterectomy

Autores: James Olukayode,Olopade; Hyelduku Danladi,Kwari; Isabella Onome,Agbashe; Silas Kalu,Onwuka.
A comparative study of ocular morphometry was done in goats in Nigeria using the three major breeds. The result showed that the circumferences (mediolateral and anteriorposterior) were fairly constant between the breeds. The mean relative eyeball weight ranged from (0.39 ­ 0.59) x 10-3. Asymmetry was observed between the right and left eyeball weights and circumferences in all breeds and there was disparity in the asymmetry. It was also observed that heavier eyeball weights did not always correspond to a wider circumference. Female WAD and RS goats had significantly heavier (p &lt; 0.05) eyeball weights than the males but that was not the case in the Sahel breed. Animals above one year had consistently higher values in most of the parameters examined on...

Location of the cytoplasmic droplets (CD) and their dimensions varied significantly (p&lt;0.01) when sperm cells traverse through the regions of caput, corpus and cauda epididymis and vasdeferens respectively. The gradual diminution in the morphology of CD between the epididymal regions were related significantly (p&lt;0.01, p&lt;0.05). Caudal shift of the CD, along with regression in size and finally their exclusion from the sperm cells reflected one of the most important events in the maturation process of male gametes in Black Bengal buck.

Provedor de dados: 77
Autores: Onar,Vedat; Belli,Oktay; Owen,Pamela R.
In the burial chamber M4 of the Van-Yoncatepe necropolis in eastern Anatolia, dated to the beginning of the first millennium before our time, fox skeletal remains have been discovered together with human skeletal remains. The fox remains consist of two skulls and a large number of skeletal (postcranial) bones. Examination of the material led us to the conclusion that five foxes had been buried in the chamber. Craniometric and osteometric measurements were carried out on the bones, and estimations of shoulder height and body weight have been calculated. Evaluation of all quantitative and qualitative data and comparison with modern fox species led to identification of the remains as red fox (Vulpes vulpes)

Study of Wool Characteristics in the Aranese Ovine Breed
Provedor de dados: 77
Autores: Parés,P.M; Jordana,J; Pérezgrovas,R.
To date, no ethnological study on the wool characteristics of the Spanish Aranese ovine breed has been published. Fifty three animals belonging to this breed are tested as fleece samples. Each sample is analyzed for fleece type and length, yield by isoalcohol scouring, fiber length for each kind of fiber, variation in fiber diameter, and proportions of non-medullated and medullated or kemp fibers. Fiber length appears shorter than that previously reported for the breed by other authors. Fleeces of the Aranese sheep breed can be described as square, simple, "semi-open" and short with a relatively high yield by isoalcohol scouring and low medullation levels, thus indicating good potential quality and greater suitability for potential processing than other...

Intraparotid Facial Nerve Neurofibroma: an Uncommon Neoplasm
Provedor de dados: 77
Autores: Sethi,Ashwani; Chopra,Shamit; Passey,J. C; Agarwal,A. K.
Intraparotid facial nerve neurofibromas are a rare entity, and are grossly and histopathologically distinct from the comparatively more prevalent schwannomas. We report a rare case of an intraparotid facial nerve neurofibroma with intratemporal extension in a 48-year-old female. The tumor was surgically excised with cable grafting of the facial nerve. Electroneurography may eventually assist in the preoperative diagnosis. Facial nerve resection should be more readily contemplated in a patient with neurofibroma than in a patient with schwannoma; however, facial nerve preservation with serial follow-up electroneurography and computerized tomography remains a viable option in patients with small facial nerve neurofibromas when electrical testing reveals...

Easy and Unbiased Determination of the Maxillary Sinus Volume
Provedor de dados: 77
Autores: Coronado,Cesar; Arriagada,Oscar; Suazo Galdames,Iván.
Determining the volume of the maxillary sinus is necessary in certain procedures. We present a simple method for estimating the volume of the maxillary sinus from groups 3, 5 and 9 coronal CT scan using the Cavalieri method combined with systematic sampling and evaluated randomized images. We used 10 dry skulls submitted to the TC. The actual volume was determined using silicone adapted to the maxillary sinus cavity. The estimated volume showed a high correlation with real volume, with no differences between groups. We concluded that it is possible to estimate without bias and with high accuracy the volume of the maxillary sinus from a minimum of 3 CT images obtained through randomized systematic sampling and the proposed method.

Cleidocranial Dysplasia: A Case Report
Provedor de dados: 77
Autores: Alves,Nilton; Oliveira,Reinaldo de.
The cleidocranial dysplasia is a rare disease which can occur either spontaneously or by a dominant autosomal inheritance, with no predilection of genre or ethnic group. The odontologist is, most of the times, the first professional who patients look for to solve the problem, since there is a delay in the eruption and /or an absence of permanent teeth. In the case related in this work, this was the reason why the patient looked for treatment. Many others odontological problems are also present in this syndrome, such as, supernumerary teeth, retained teeth, with shape deviation and absence of deciduous teeth resorption. The premature diagnosis allows a proper orientation for the treatment, offering a better life quality for the patient.

We dissected the shoulders of 20 human foetuses to anatomical study. The purpose of this study was to characterize the anatomical origin of the long head tendon of the muscle biceps brachii (LHBBT) in human foetuses and its relationships with the glenoid labrum of the scapula. The results had shown that in approximately 95% of the cases the tendon of the long head of the biceps brachii inserts in the region of the glenoid labrum. This origin seems to form, together with the glenoid labrum, an anatomical complex. We conclude that the almost totality of the LHBBT was originated in the glenoidal labrum. For us, this furthermore reinforce the importance and necessity of better clarifying the anatomical and clinical implications of the biceps/labrum complex.

Many of the anatomical variations that are inadequately described or quantified are actually more clinically and surgically significant than being just anatomical curiosities. We report about such a variation where an aberrant slip existed in the scalene group, in a 56 year old embalmed female cadáver. This kind of variation may affect the size of the scalene triangle, and thus, may potentially result in varied signs and symptoms in patients vulnerable to thoracic outlet syndrome (TOS). Proximity of the scalene muscles to the brachial plexus, subclavian artery and vein, coexisting with aberrant slips or bundles may also predispose to compression syndromes.

Si bien la tradición ha consagrado el término "tricúspide" para caracterizar a la valva atrioventricular derecha, numerosos estudios han demostrado la gran variabilidad de presentación de ésta, describiéndose casos con dos y, situaciones extremas, con seis velos valvulares. Parece existir una relación directa entre el incremento del número de válvulas y la morbimortalidad de los portadores de esta variación anatómica. En este trabajo presentamos una valva atrioventricular derecha con dos velos valvulares, estructura donde es posible identificar claramente el componente septal con una sola válvula y el componente mural que se descompone en una extensa válvula anterior y una pequeña válvula comisural anteroseptal

In order to describe the morphology of the kidney and implement its dissection technique, specimens of the grey snapper Lutjanus griseus were analyzed. The morphology of the kidney fits with the structural pattern of the higher teleosts, consisting of a large fusion of the right kidney with the left, with the exception of the anterior renal lobes. Both anterior renal lobes are separated by the retractores dorsales muscles and by the anchorage of the gas bladder to the vertebrae. Some cranial and spinal nerves, as well as ribs, blood vessels, the Baudelot's ligament, the sinus venosus of the heart, the precaudal vertebrae, and the gas bladder mark the surface of the kidney. The archinephric ducts are connected with the urinary bladder, from which the common...

Andreae Vesalii: The Temporomandibular Joint
Provedor de dados: 77
Autores: Vasconcellos,Henrique Ayres de; Barros de Vasconcellos,Pedro Henrique.
The Temporomandibular Joint (TMJ) has been studied for many years since the finding of mummies and fossils. In Egypt of the pharaos, papyrus from the year 3000 B.C. remark the care in which a luxation of the TMJ should be undertaken. In India, at the beggining of the Christian age, in Hipocrates' Greece and in Pergamo of Galenus the TMJ has also been the focus of several studies. But it was Vesalius (Andreae Vesalli), with his particular teaching methodology and publication of his masterpiece De Humani Corporis Fabrica, who showed the way to study Human Anatomy as it is done today. The description of the face bones, of the articular disc and the muscles used for chewing are all a contribution from Vesalius to the anatomic-functional study of TMJ

Multiple Anatomical Variations of the Hepatic Pedicle: Case Report and Clinical Application
Provedor de dados: 77
Autores: Bianchi,Homero Felipe; Algieri,Rubén Daniel; Sanjurjo,Daniela; Ottone,Nicolás Ernesto; Fuentes,Ramón.
The knowledge in detail of the anatomy of the hepatic pedicle is critical when operating it and its surroundings. The presence of anatomic variations is higher at the arterial component level than at the bile component level or venous component level, which in the 90% of the cases it appears as the classic description. The presented case in this work implies a very low frequency of appearance. For this reason, the surgeon must be alert at the moment of making a decision so as to avoid injuries that may put the patient´s life at risk.

Ordenar a lo largo del tiempo desde épocas remotas hasta el tiempo de Galeno -siglo II- las ideas imperantes sobre los nervios. Se revisaron variadas fuentes bibliográficas sobre los nervios y se ordenaron en el tiempo hasta el siglo II en relación a los conceptos sobre la constitución y funcionalidad de los nervios, comparando dichas ideas y conceptos. Históricamente se muestra que con el avance de la cultura escrita y con el lento desarrollo de nuevas ideas, tuvo que transcurrir varios miles de años para que se llegara a una mejor comprensión menos filosófica mediante la experimentación anatomo-funcional de estos elementos del sistema nervioso.

Autores: Xie,Zhaohui; Zhang,Rui.
The dorsal surface of the tongues of the Slow Loris and the Pygma Slow Loris were examined by employing scanning electron microscopy techniques. Three types of the papillae are present on their dorsal surface of the tongue: filiform, fungiform and vallate. The filiform papillae are located the apex and the body of the tongue, and we observed that each of them has a gustatory pore. The fungiform papillae, scattered singly among the filiform papillae, distribute mainly on the apex of the tongue. The vallate papillae are located along the diversing arms of the V-shaped boundary between the anterior and posterior regions of the tongue. In addition, no foliate papillae were observed. The morphological characteristics of the dorsal surface of the tongues in Slow...

Elasmobranchs are important, not only as an economic resource but also for their phylogenetic position. Their slow growth and long reproductive cycles, together with the high fisheries pressure exerted, attempt to the knowledge of all biological parameters of species. In this work we analyze the histology of the pregnant uterus of the gatuzo, a viviparous aplacental shark. The mucosa depicts modifications similar to those of placental species and others proper of histotrophism. Likewise, a network-like muscular layer in the mucosa was described for first time in the genus. The presence of vitelline plates in the gut of at term embryos suggests that the maternal supplies are not enough for the big fetus development. The relationships between maternal...

A Brief Review on the History, Methods and Applications of Plastination
Provedor de dados: 77
Autores: Pashaei,Shahyar.
Plastination is a process of preservation of anatomical specimens by a delicate method of forced impregnation with curable polymers like silicone, epoxy or polyester resins with vast applications in medical fields of study. Plastination is a technique of tissue preservation developed by Dr. Gunther von Hagens in 1977. In this process, water and lipids in biological tissues are replaced by curable polymers (silicone, epoxy, polyester) which are hardened, resulting in dry, odorless and durable specimens. In this technique it is possible for us to treat every part of the body and tissues to preserve it for educational purposes. Nowadays there are new and vast varieties of applications for plastination in the educational and cultural areas. This invention has...

Study About the Development of the Temporomandibular Joint in the Human Fetuses
Provedor de dados: 77
Autores: Alves,Nilton.
The temporomandibular joint (TMJ) is a highly specialized articulation that differs from all the other synovial articulations for many reasons. In children, different from what we observe in adults, these articulations have rarely been studied under the morphofunctional aspect, mainly in the embryonary and fetal stages. In this study 10 fetuses with ages varying from 16 to 39 weeks of intrauterine life were used, and it could be observed that the fibers and thickness of the articular disc, as well as the articular capsule and the condylar process, suffer modifications according to age. It was also observed that the superior head of the lateral pterygoid muscle inserts itself in the articular disc and capsule in all the ages studied. Also, the maturation of...

Variations of vessels and nerves in the left neck side, of 65 year old male cadaver, during the routine dissections, were detected. It was observed that the linguofacial trunk originated from external carotid artery and that the ascending pharyngeal artery originated from the occipital artery. It was determined that after the laryngeopharyngeales rami originated from the superior cervical ganglion, the branch wound around the origin of the superior thyroid artery. As an additional variation, the internal jugular vein divided. The cervical ansa and the inferior belly of the omohyoid muscle passed through the parts of the vein. We think that these type of variation can entail important difficulties during radiologic and surgical procedures of the neck...

The aorta is the main arterial trunk in the human body, however, its variation was extremely variable. During an educational dissection, aberrant branching pattern of aortic arch was found in a Korean cadaver. The brachiocephalic trunk (innominate artery) originated from the aortic arch at the left side of the trachea. It crossed the trachea and divided into the right common carotid and subclavian arteries. The left vertebral artery originated from the aortic arch between the origins of the left common carotid artery and the left subclavian artery, then the left vertebral artery coursed upward to the transverse foramen of the C7. The author describes this previously novel case report with aberrant brachiocephalic trunk and left vertebral arteries and...

Autores: Garbelotti Junior,S; Yukio Fukuda,T; Rodrigues Pereira,V; Garcia Lucareli,P; Olave,E.
Knowledge of anatomical variations of the musculoskeletal system is important for interpreting unusual clinical presentations. We observed the presence of an abnormal extensor indicis muscle in the left hand of an adult male cadaver. In this case, the muscle comes from the ligament and over the scaphoideum and trapezoideum bones and continues after the short muscle belly; it is attached to the dorsal aponeurosis of the indicis. This muscular disposition was described in other studies which demonstrated approximately 1.0% of incidence. Clinically, this anatomical variation may be associated with pain and swelling at the back of the hand. In these cases symptoms tend to increase due to mechanical stress and can be confused with the presence of a dorsal...

Autores: Pitol,Dimitrius Leonardo; Issa,Joao Paulo Mardegan; Caetano,Flávio Henrique; Lunardi,Laurelúcia Orive.
The Phrynops hilarii specie of turtle has its characterization not well defined in the literature, it was proposed in this study the leukocyte characterization of the blood, stained by Leishman and analyzed under light and transmission electron microscope. It was not observe any cellular type with similar characteristics to neutrophils in mammalian group. We believed, based on the data obtained in this study that the heterophils have a morphofuncional analogy with another neutrophils belonged to mammalian group. This conclusion is being supported in many recent studies found in the literature

Provedor de dados: 77
Autores: Jerbi,Hassen; Pérez,William.
The barbary stag is an intermediate feeder ruminant of the Cervidae family. The macroscopic anatomy of the stomach in one adult barbary stag was described. The stomach of the barbary stag was composed of the four classic compartments of the ruminants. The weight of the full stomach was 10.5 Kg. The ruminal papillae were distributed unevenly in the rumen. The maximum height of the cristae reticuli was 0.2 cm. The cellulae reticuli were mostly undivided. The curvatura omasi measured 15.0 cm and the omasum had 15 primary, 10 secondary, 10 tertiary and 17 cuaternaryLaminae omasi. The abomasum had about 12 plicae spirales abomasi.We concluded that the stomach morphology of the barbary stag had characteristics of other intermediate feeder ruminants.

Provedor de dados: 77
Autores: Jalili,C; Khani,F; Salahshoor,M. R; Roshankhah,S.
Nicotine consumption can decrease fertility drive in males through inducing oxidative stress and DNA damage. The color of turmeric is because of a substance called curcumin for which some anti-oxidative and anti-inflammatory properties have been identified. In this study, various doses of curcumin (10, 30 and 60 mg/kg) and curcumin plus nicotine (10, 30 and 60 mg/kg) were administered intraperitoneally to male mice for 28 consequent days and reproductive parameters were determined. The results indicated that nicotine administration (0.5 mg/kg) significantly decreased testosterone level, count and motility of sperms, and testis weight compared to control group. However, increasing the dose of curcumin significantly increased reproductive indices in most of...

Provedor de dados: 77
Autores: Taheri,Mohammad Mehdi Hassanzadeh; Afshar,Mohammad.
Variations of the terminal branches of the brachial plexus in the upper limb are abundant and frequently have been reported. But connection between its radial and ulnar nerves at humeral level is very rare. During routine dissection of the right arm of a 75-year-old male cadaver in the Department of Anatomy of Birjand University of Medical Sciences (BUMS), in Iran, we observed a connection between radial and ulnar nerves, and from the literature reviewed, we found only two cases that had been reported previously, one of them was unilateral and the other bilateral. Awareness of such variations are very important for surgeons and diminish the possible complication of regional anesthesia and surgical procedures, hence, we decided to report it.

Aspectos Moleculares en la Formación de la Cara y del Paladar
Provedor de dados: 77
Autores: Montenegro,María Angélica; Rojas,Mariana.
En mamíferos, la adhesión y fusión de los procesos faciales y palatinos, son mecanismos esenciales en el desarrollo del paladar primario y secundario. La falla de cualquiera de estos procesos trae como consecuencia la formación de labio leporino o fisura palatina. En ambos casos, los procesos opuestos adhieren a través de desmosomas para formar una lámina epitelial media la cual desaparece por transformación epitelio-mesenquimática. La apoptosis ocurre sólo en las células del periderma. En el paladar secundario, estos procesos están regulados por TGFß-3, pero este factor no está presente en los procesos maxilares o nasales que forman el paladar primario, por lo cual en la formación del labio actuarían otros factores tales como Shh (sonic hedgehog) y BMP...

Autores: Guzmán,Rodrigo A; Silvestre,Rony A; Arriagada,David A.
Among the sequelae of central nervous system injury is spasticity which is difficult to manage in rehabilitation. Current treatments consider the administration of the botulinum toxin. However, results have proved highly variable in terms of effectiveness, attributable to the distance between the injection site and the innervations-zone (IZ). High Density sEMG (HDsEMG) has been used to gather information about muscle physiology and for location of the IZ. The aim of this study was to characterize the IZ of the biceps brachii muscle in healthy subjects during isometric contraction. We assessed the biceps brachii muscle of twenty healthy subjects (n=20) using a 64 surface electrodes matrix. The average location of the IZ was 34% distal to the line between...

Ratas malnutridas prenatalmente con una dieta isocalórica y baja en proteínas, presentaron un menor diámetro axonal promedio en el esplenio callosal que los animales control, tanto de las fibras mielínicas como amielínicas. También se observó una mayor densidad axonal promedio, con respecto a los controles. Estas observaciones sugieren que: 1) las conexiones cortico-corticales (interhemisféricas) son vulnerables a la malnutrición proteica; y 2) lo anterior tendría incidencia en la velocidad de conducción interhemisférica, en particular con lo que dice relación con las conexiones visuales

Octopus mimus (MOLLUSCA: CEPHALOPODA) EMBRYO MISDEVELOPMENT DUE TO CHRONIC EXPOSURE TO THE ORGANOSPHOSPHORUS PESTICICE PARATHON
Provedor de dados: 77
Autores: Gutiérrez-Pajares,Jorge L.; Olivares,Alberto; Bustos-Obregón,Eduardo.
Pesticides are of ample worldwide use. At present there is a growing concern about seawater contamination by these chemicals. Developing aquatic organisms are particularly at risk. For this reason, early development of Octopus mimus embryos under exposure to commercial Parathion was examined. Concentrations over 0.4 mM of the pesticide altered formation of the embryonic disc at the blastula stage, resulting in abnormal gastrulation and arrest of further development. This toxic effect may be due to the blockade of DNA synthesis elicited by organophosphoric pesticides causing diminished number of blastodermic cells at the time of epiboly, thus hindering the start of invagination. Seawater contamination seems, therefore, of relevance for survival of exposed...

Facial palsy, parotid diseases and others are a relatively common clinical condition with a variety of causes. Irrespective of its etiology, facial palsy always represents a very serious problem for the patient. Parotid gland diseases also are very common occurrence. In this particular case, the knowledge of surgical anatomy of the facial nerve and its correlations with the parotid gland is very important for an adequate preservation in the cases of surgery of benign and malignant diseases of the parotid gland. Although the surgical anatomy of the facial nerve has been well documented, the concept of surgical treatment for parotid tumors, facial palsy (neurorraphy techniques) and submandibular surgical approach are rarely challenged now.

The laboratory rat (Rattus norvegicus albinus) has been used as a model for medical, biological and molecular research, for a long time. It is an interesting fact that there are no detailed descriptions of the gross anatomy of the liver and its ways of fixation. The aim of this study is to define clearly and according to the Nomina Anatomica Veterinaria principles, the liver and its way of fixation in this species of laboratory mammal. Eighty-eight rats (Rattus norvegicus albinus) were used, with a weight between 250 and 450 g. They were dissected in fresh, after been euthanized by an overdose of thiopental sodium intraperitoneal. An incision from the xiphoid cartilage up to the pubic region was made and another on each costal arch toward dorsal.

Autores: Zhang,Zihui; Yang,Yan.
Morphological work on the appendicular myology of birds forms the basis for comparative, functional and systematic studies, but our knowledge of the descriptive anatomy of birds is still very incomplete. The musculature of the wing muscles of the Golden Pheasant (Chrysolophus pictus), an endemic species of China, is studied in detail. All wing muscles are present as in other Galliformes. Myological characteristics including the absence of a deep layer of M. pectoralis pars thoracicus, well development of anterbrachial muscles, as well as the occurrence of a distinct fleshy slip from the proximal belly of M. biceps brachii, are suggested to be associated with its flapping flight. This paper is the prelude to functional analysis on muscle architecture in...

Insertion of the Superior Head of the Lateral Pterigoid Muscle in the Human Fetuses
Provedor de dados: 77
Autores: Altruda Filho,Luiz; Alves,Nilton.
The lateral pterygoid muscle, more specifically its superior head, as we know, is closely related to the temporomandibular joint (TMJ). Particularly in children, in contrast with what was observed in adults, these joints have been rarely studied, by the anatomic functional aspect, little knowing about its functions in the embryonic and fetal periods. We used, in this work, 12 fetuses ranging in age from 16 to 39 weeks of intrauterine life, where we observed that the superior head of the lateral pterygoid muscle is inserted in the disc and in the articular capsule, in all age groups studied, and also, that the fibers and the thickness of the articular disc is, as well as the articular capsule suffer modifications in accordance with the period of development

Cephalic and facial indices are used to estimate the racial and sex differences. This study was carried out to establish standards for craniofacial variables and distribution of cephalic and facial indices in Kosovo - Albanian population. The study population consisted of 204 dental students (101 males and 103 females, aged 18 to 30). Four basic craniofacial variables (head length, head breadth, morphological face height and face breadth) were measured to obtained cephalic and facial indices. All measured craniofacial variables are considerably higher in males than in females (p&lt;0.0001). In the Kosovo ­ Albanian population brachycephalic type of head (44.61 %) and hyperleptoprosopic type of face (63.34%) prevail.

A comparative study of skull types was done using 65 skulls obtained from three different goat breeds in Nigeria namely; Red Sokoto, Sahel and West African Dwarf. A unique depression was consistently found at the cornual end of the temporal line of the skull medial to the middle portion of the caudal boundary of the orbit and dorsal to the lateral portion of the parietofrontal suture. The depression was found in all the breeds studied, and in both sexes on the lateral sides of both cornual processes of the frontal bones. The features (depth, height and width) of the depression were found to vary without regard to either sex or breed. A search of the literature did not yield any information on this depression in the skull of the goat. Consequently, we...

Identifying the maturity stage of specimens is essential for the determination of the spawning season, which in turn facilitates the formulation of adequate fisheries management measures for the sustainable use of sea resources, such as abalone. This study aims to validate, based on histological evidence, a gonad maturation scale that encompasses four morphochromatically-defined stages (developing, maturity, spawning and resting) for females and males, plus an additional stage for reproductively inactive (undifferentiated) specimens, to be used as an identification key. Given the similarity between Haliotis fulgens and Haliotis corrugata as to their morphochromatic features, the gonadal maturation scale can be used for both species.

Preoperative Computed Tomographic Evaluation of Inferior Nasal Concha Hypertrophy and its Role in Deciding Surgical Treatment Modality in Patients with Deviated Nasal Septum
Provedor de dados: 77
Autores: Mrig,Sumit; Agarwal,A. K; Passey,J. C.
Deviated nasal septum is associated with compensatory hypertrophy of the inferior nasal concha on the contralateral side. In the past conventional septoplasty was done for the deviated septum, which would improve the patency on the side of deviation but would worsen it on the opposite side due to reallocation of the septum to the midline. The present study of 50 patients unfolds the anatomical composition of the inferior nasal concha based on the computed tomographic scan and help the otolaryngologist to determine whether to add turbinoplasty to standard septoplasty procedure or not.

Autores: Sripanidkulchai,Kittisak; Chaisiwamongkol,Kowit; Iamsaard,Sitthichai.
In submental and around the mouth areas, the superfacial muscles are considered in surgery of some deformities of mouth angle. Herein, we report a rare case of the Transversus menti muscle (TM) in a Thai 74 year-old male cadaver. This TM originated from both sides of the oblique line of depressor anguli oris and formed as transverse fibers in submental area. Their fiber ran under the chin and was superficial to platysma muscle. The TM was innervated and supplied by mandibular branches of facial nerve and small branches of the submental artery. This report attempted to discuss the possible function and clinical significance of the TM.

Unusual Relation of the Median Nerve with the Accessory Head of the Biceps Brachii Muscle: An Original Case Report
Provedor de dados: 77
Autores: Mas,Nuket; Pelin,Can; Zagyapan,Ragiba; Bahar,Hakan.
During the laboratory dissection of the brachial region and the arm, an abnormal relation of median nerve with the accessory head of biceps brachii muscle has been observed unilaterally on the right upper limb of a male cadaver. Whereas the short and long heads have their normal origin, additional-excess third head originated from the anteromedial surface of the superior part of the humerus. Some fibers of this accessory head on the medial side arise from the deep fascia surrounding the brachialis muscle. The fibers then cross the median nerve superficially before joining the third head which has inserted into a common tendon together with the long and short heads. To have information of such variations is of importance either for anatomists or clinicians...

Desarrollo del Aparato Digestivo
Provedor de dados: 77
Autores: Roa,Ignacio; Meruane,Manuel.
El aparato digestivo deriva del endodermo y el mesodermo, que forman su epitelio y la musculatura lisa respectivamente. Al igual que en el resto de los sistemas, existe un interacción epitelio-mesenquimática mediada por moléculas como Hedgehog, BMP y FoxF1 que determinan el crecimiento intestinal en sus ejes principales. Los genes Hox, junto con el resto de las moléculas, participan en la regionalización del sistema digestivo. En sus inicios lo denominaremos intestino primitivo, formado por un tubo endodérmico que deriva del saco vitelino; dividiéndose en intestino anterior, medio y posterior. En esta revisión veremos cómo estos 3 segmentos darán origen a las diferentes estructuras del sistema digestivo en los vertebrados.

Provedor de dados: 77
Autores: Carrasco,Vanessa; Martínez,Cristián; Silva,Héctor; Collipal,Erika; Campos,Christian; Silva,Tamara.
Obesity is a prevalent disease in Chile. The multitude of cause factors makes it a complex disease and therefore very difficult to treat, since its roots lie in the earliest stages of life. We evaluated pupils from 21 municipalized primary schools, in rural and urban communities from the 10 districts of the IX Region. The sample consisted of 275 subjects in Kindergarten and first year primary school in the year 2008, who were monitored over two years. The results show a trend indicating an increase in the prevalence of obesity in the sample, the difference being statistically significant, p=0.000. These results show that obesity is increasing, and that more action is needed to slow this disease occurring from early childhood.

Facial involvement in patients with rheumatoid arthritis is variable depending on the type, onset, and duration of the disease. The treatment of patients with open bite resulting from degenerative changes on the condyles can be a challenge for the surgeon. Rheumatoid arthritis is a systemic disorder of unknown etiology characterized by chronic inflammation and proliferation of synovial tissue. Studies showed that patients with rheumatoid arthritis can developed progressive osteoarthrosis that result in gross radiographic changes in the condyles. With the development of distraction osteogénesis for treatment of mandible hypoplasia a new chapter has been opened in the surgical management of patients with rheumatoid arthritis associated with skeletal...

Provedor de dados: 77
Autores: Olopade,J. O.; Onwuka,S. K.
The study involved the measurements of some clinically important landmarks for regional anesthesia in the head of twenty five Red Sokoto goats. The length and maximum height of the mandibles were 12.7cm and 7.7cm respectively. The distance from the mandibular foramen to the base of the mandible was 3.0cm while the distance between the lateral alveolar root and mental foramen and from the facial tuberosity to the infra-orbital foramen was 1.8cm in both instances. The data was discussed with regard to its importance in proper tracking of some nerves in aid of regional anaesthetic procedures in the head of the Red Sokoto goat and was compared with our results reported for the West African Dwarf breed

Provedor de dados: 77
Autores: Anu,Vinod Ranade; Rajalakshmi,Rai; Latha,Venkatraya Prabhu; Mangala,Kumaran.
An unusual presentation of the duplication of thoracic duct with a rare lymphatico- venous communication was found during the routine dissection for undergraduate students. The thoracic duct duplicated at the level of T12 vertebra. Normally thoracic duct opens into the junction of left internal jugular vein and subclavian vein. On the right side of the neck, the right lymphatic duct conveys the lymph from the head and neck, the upper extremity and the right side of the thorax to the right innominate vein. Here, the duplicated thoracic duct on the left side opened directly into the inferior vena cava. The above case is discussed with regard to its development, incidence, and clinical significance

Provedor de dados: 77
Autores: Rai,Rohan; Rai,Ashwin R; Rai,Rajalakshmi; Bhat,Keshav; Muralimanju,B. V.
Disturbance in the organogenesis of tongue might lead to some malformations like tongue tie, bifid tongue and hairy tongue. Severe degrees of these anomalies may cause speech impairment or periodontal defects. The present study was done on patients of the southern coastal belt of India during the past two years, on gross tongue anomalies. The results of the present study reveal that occurrence of tongue tie is 0.2% and bifid tongue is 0.3% in the southern coastal population. Since great majority of these oral anomalies have genetic basis the purpose of the present report is to highlight that these anomalies can exist without any familial background and also to suggest that environmental factor may play a role in the etiogenesis of these anomalies.

The First Metacarpal is the Thumb First Phalange: EvoDevo Implications
Provedor de dados: 77
Autores: Valenzuela,Carlos, Y; Berríos-Loyola,R; Canals,M.
We examined the status of the first metacarpal bone whose shape, fetal and post-natal development correspond to those of the thumb proximal phalanx. Galen already described this, circa 170 CE. Our radiographic data confirm that the pre-axial (radial or anterior) side of the hand matures, later than the post-axial (ulnar or posterior) side, both, pre- and post-natally. A new perspective on thumb primate and human ontogeny is discussed and comparative observations on the Evolutionary Development (EvoDevo) of the thumb and the first toe are proposed along with a nomenclature honoring Galen's original proposition.

Provedor de dados: 77
Autores: Yuan,Guoqiang; Pan,Yawen; Li,Haiyan; Wang,Jianlin.
Vascular endothelium play an essential role in regulating endothelial functions by maintaining normal vascular tone, modulating hemostasis, and preventing thromobogenesis. The aim of present study was to reveal ultrastructure features of coronary artery endothelium in Bactrian Camels by means of scanning electron microscope (SEM) technology. The results showed that the endothelial cells distribute along the direction of blood flow. Their morphology and protuberant degree towards luminal surface vary for different parts of the coronary artery. The luminal surface of a.c oronaria sinistra and a. coronaria dextra was covered by impaired and intact endothelium, respectively. Platelets and leukocytes sticking to the endothelium were found.

The stereoscopic morphology of the iliofemoral, pubofemoral, and ischiofemoral ligaments in hip joint is hard to understand, either in anatomy books or from cadaver dissection. To aid in understanding, three-dimensional models were built from the sectioned images of cadaver hip, which demonstrate fine components better than CTs and MRIs. In the female data of Visible Korean project, the ligaments and neighboring structures were recognized and outlined in detail. Successively, the outlines were stacked and reconstructed to manufacture their surface models by using the sophisticated computer method. The surface models were overlapped with the original sectioned images, which enhanced comprehension of the hip joint anatomy. With the surface models, hip joint...

Autores: Hipkaeo,Wiphawi; Kondo,Hisatake.
In embedment-free transmission electron microscopy without employing epoxy embedding media, the cytoplasmic matrix, in which cell organelles and elements including the cytoskeletons are held in place, lattices of strands are clearly and constantly disclosed in every cell. Their compactness is variable in different kinds of cells and in different domains of one and the same cell, and it is changeable under hypo- or hyper-osmolarity. In addition, the appearance of strand-lattices is duplicable in artificial proteins at different sol/gel states and concentrations. All taken together, a new and probable ultrastructural criteria has been proposed for identification of cytoplasmic sol/gel states with a hope that the dynamic properties of the cell is understood...

Autores: Muñoz,L; Concha,M. L.
Los organismos multicelulares se desarrollan a partir de una sola célula: el cigoto. A lo largo de su ontogenia, las células que derivan del cigoto despliegan distintos programas celulares, los cuales son estabilizados por mecanismos epigenéticos. Los programas de las células troncales son más inclusivos, siendo mayor el silenciamiento que la activación de genes durante el proceso de diferenciación celular. Experimentalmente, se ha logrado que células en estado de diferenciación terminal reactiven el programa de células troncales y recuperen su pluripotencialidad, proceso llamado reprogramación. Esto despierta esperanzas en el avance de una medicina regenerativa con nuevas capacidades para el tratamiento de enfermedades crónicas, sin las restricciones...

Autores: Ofusori,David A; Okwuonu,Christina U; Ude,Raymond A; Adesanya,Olamide A.
This report describes an adult male cadaver with dextrocardia and situs inversus totalis in a Nigerian cadaver. The photographic illustrations revealed transposition of some of the visceral organs such that the stomach and spleen were located on the right and the liver and gall bladder on the left. Also, the left lung was tri-lobed while the right was uni-lobed. The heart was flattened and flipped to the right thus, transposing the great vessels. The report showed that dextrocardia and situs inversus exists amongst Nigerians and possibly Africans and therefore wish to recommend early medical examination since patients with this condition are unaware of their unusual anatomy until they seek medical attention for an unrelated condition.

Autores: Alves,Nilton; Deana,Naira Figueiredo.
The discomaleollar ligament is not described in the anatomy textbooks but was demonstrated by Pinto (1962) and others. It is a ligamentous structure connecting the malleus in the tympanic cavity and the articular disc and the capsule of the temporomandibular joint. This anatomical relationship between the middle ear and temporomandibular joint is supposed to be one of the explanations for the otological symptons associated with temporomandibular joint dysfunction. The aim of our study was to determine the frequency of occurence of the discomaleollar ligament. Twenty hemi-heads of adults human were carefully dissected from a superior approach through the middle cranial fossa. The bone of the middle cranial fossa over the temporomandibular joint region and...

Effects of Sensory Stimuli on Postural Control: a Tetraplegic Case Report
Provedor de dados: 77
Autores: Gatica R,Valeska; Elgueta C,Edith; Valdés M,Ramón.
During sessions of physical therapy, a tetraplegic patient with incomplete spinal cord section at C5 level was found to have changes in the posture post intervention. The therapy consisted of tactile stimulation in specific points of his body to genérate reflex patterns of muscle activation (Vojta therapy principies). To quantify these postural changes in the subject, the center of pressure displacement in sitting posture was measured. An analysis of the changes observed in postural control through fourteen months of follow-up is presented and discussed in the report bellow.

Ulnar and Humeral Heads Forming Separate Bellies: A Rare Case of Digastric Flexor Carpi Ulnaris Muscle
Provedor de dados: 77
Autores: Rao K. G,Mohandas; Bhat,Seetharama M; Venkataramana,V; Rodrigues,Vincent.
Proper knowledge of muscular variations is essential for both anatomists and surgeons. Variations of the flexor carpi ulnaris (FCU) are not very common. We are reporting an unusual case of FCU muscle with two bellies. The two heads (ulnar and humeral) of the muscle continued as two separate bellies and the tendons of which joined each other slightly proximal to the wrist before getting inserted to pisiform bone. Further, detailed literature review of variations of FCU muscle is done and the developmental basis for the variation and its surgical importance are discussed.

Ultrastructural Study of the Neuromuscular Junctions of Extensor Digitorum Longus Muscle (M. extensor digitorum longus) of the Mice
Provedor de dados: 77
Autores: Boaro,Sueli N; Fragoso Neto,Raul A.
The neuromuscular junction of the extensor digitorum longus muscle of fingers was analyzed in 21 young (three months) and old (from six to 25 months) mice, from both genders. Morphologic changes were found throughout the mouse life, being more frequent and visible with aging. According with the data described in the literature consulted and the observations taken in this research, it becomes clear that a continuous process of morphological remodeling occurs in all neuromuscular ultrastructural junctions of the extensor digitorum longus muscle of fingers, during the life of the animal. Theses changes are characterized by figures of myelin in the cytoplasm of Schwann cells, pleomorphic and multivesiclar bodies, mitochondrias with morphologically altered...

Bilateral Presence of Axillary Arch Muscle Passing Through the Posterior Cord of the Brachial Plexus
Provedor de dados: 77
Autores: Pillay,Minnie; Jacob,Suja Mary.
The axillary arch can be described as an anomalous muscular slip of latissimus dorsi muscle. In this paper, a rare case of bilateral axillary arch is reported during routine dissection of the axillary region of a 57-year old male cadaver. On both sides, the axillary arch muscle took origin from latissimus dorsi and teres major, and passed upwards through the posterior cord of the brachial plexus, but posterior to the bulk of axillary neurovascular bundle. It then split into two slips: the medial slip was inserted into the root of the coracoid process, while the lateral slip which was intracapsular, was attached to the lesser tubercle, above the attachment of subscapularis. The presence of the muscle has important clinical implications, and the position,...

Niels Stensen and the Discovery of the Parotid Duct
Provedor de dados: 77
Autores: Strkalj,Goran.
Niels Stensen was a renowned Danish scientist, theologian and Catholic bishop. Stensen's early career was devoted to anatomy and it is in this discipline that he made many important contributions. His method in anatomy was rooted in systematic observations based on meticulously executed dissections of human and animal cadavers, as well as experiments on animals. His first important discovery in the field of anatomy, which is the main focus of this paper, was the discovery of the parotid duct. The discovery brought Stensen recognition and fame but only after a controversy in which he was accused of plagiarism by his mentor Gerard Blaes. Although still in an early stage of his career Stensen dealt with the accusation masterfully, producing further research...

Current perspectives on the evolution of birds
Provedor de dados: 16
Autores: Ericson, P.G.P.
The paper summarizes the current understanding of the evolution and diversification of birds. New insights into this field have mainly come from two fundamentally different, but complementary sources of information: the many newly discovered Mesozoic bird fossils and the wealth of genetic analyses of living birds at various taxonomic levels. The birds have evolved from theropod dinosaurs from which they can be defined by but a few morphological characters. The early evolutionary history of the group is characterized by the extinctions of many major clades by the end of the Cretaceous, and by several periods of rapid radiations and speciation. Recent years have seen a growing consensus about the higher- level relationships among living birds, at least as...

Cylisticus convexus, a rare synanthropic woodlouse in The Netherlands (Crustacea: Isopoda: Cylisticidae)  Until recently, the occurrence of Cylisticus convexus (De Geer, 1778) in the Netherlands was uncertain. The only certain old record dates from March 1927, when the species was collected at the coal-shed of the Zoological Museum at Amsterdam. During the last years, two specimens have been collected on semi-natural sites. Both were found on a dike, one near Everdingen, in the province of Gelderland, and one near Ritthem, in the province of Zeeland. These are the first records of C. convexus in the field. Yet the species certainly is very rare in The Netherlands. The most important morphological characteristics of the species are described and...

Blurring the picture: introductions, invasions, extinctions – biogeography in a global world
Provedor de dados: 16
Autores: Nijman, V.; Vonk, R.
Global biogeography and phylogeography have gained importance  as research topics in zoology, as attested by the steady increase in the number of journals devoted to this topic and the number of papers published. Yet, in a globalising world, with species reintroductions, invasions of alien species, and large-scale extinctions, unravelling the true biogeographic relationships between areas and species may become increasingly difficult. We present an introduction to the symposium ‘Biogeography: explaining and predicting species distributions in space and time’ held in Amsterdam in 2007, and the resulting papers as published in this special issue, including papers on crustaceans, birds and mammals.

New Scleractinian corals (Cnidaria: Anthozoa) from Sabah, North Borneo. Description of one new genus and eight new species, with notes on their taxonomy and ecology
Provedor de dados: 16
Autores: Ditlev, H.
Eight new species and one new genus of Scleractinian corals from Darvel Bay, North-western Borneo are described and illustrated. Enigmopora darveliensis, Acropora ridzwani, Lithophyllon ranjiti, Pectinia crassa, Mycedium spina, Plerogyra multilobata, Plerogyra diabolotus, and Plerogyra cauliformis. The evolutionary and distributional significance of the species is discussed. Borneo’s unique equatorial location and stable geological history are held responsible for its high diversity of corals with a number of unique species. The morphology of Enigmopora darveliensis is discussed and compared to other supposedly primitive extant corals. The endemic status of most of the Plerogyra species, with their unusually large polyps, is due to their narrow ecological...

Elders zijn zijn verdiensten geschetst als hoogleraar in de Farmacologie aan de Rijksuniversiteit te Leiden; hier willen wij even stilstaan bij zijn niet onbelangrijke verdiensten jegens de Nederlandse floristiek. Hoewel de adventieven zijn grote voorliefde hadden, is De Jongh vooral bekend geworden als de grote animator na het overlijden van Reichgelt van het Rubus-onderzoek in Nederland, wat niet alleen geresulteerd heeft in de drie „Bramenboeken”, maar ook leidde tot het oorspronkelijk onderzoek van de bramen van het Gelderse district door Van de Beek.

Autores: Gumovsky, A.
The diagnosis of the poorly known genus Kokandia Yefremova &amp; Kriskovich, 1995 (based on the single species K. salsolicola, a parasitoid of the gall midge Desertovellum stackelbergi Mamaev) is clarified and the genus is re-described. This genus is not related to Omphale Haliday, 1833 (as it was stated in the original description), because the clypeus is not delimited. The type species of Kokandia resembles species of Closterocerus Westwood, 1833, in its habitual appearance, but differs by the absence of the subtorular grooves. The main autapomorphy of Kokandia is the wide peculiar adocular flange (not seen in any other known genus of the subfamily Entedoninae). Possible relationships of Kokandia with the genera Closterocerus, Pediobopsis Girault, 1913,...

Phylogenetic reconstruction prompts taxonomic changes in Sauropus, Synostemon and Breynia (Phyllanthaceae tribe Phyllantheae)
Provedor de dados: 16
Autores: Welzen, P.C. van; Pruesapan, K.; Telford, I.R.H.; Esser, H.-J.; Bruhl, J.J.
Previous molecular phylogenetic studies indicated expansion of Breynia with inclusion of Sauropus s.str. (excluding Synostemon). The present study adds qualitative and quantitative morphological characters to molecular data to find more resolution and/or higher support for the subgroups within Breynia s.lat. However, the results show that combined molecular and morphological characters provide limited synergy. Morphology confirms and makes the infrageneric groups recognisable within Breynia s.lat. The status of the Sauropus androgynus complex is discussed. Nomenclatural changes of Sauropus species to Breynia are formalised. The genus Synostemon is reinstated.

Cricetidae (Rodentia) from the Neogene of Gargano (Prov. of Foggia, Italy)
Provedor de dados: 16
Autores: Freudenthal, M.
Hattomys, a new genus of Cricetidae, is described and three new species H. beetsi, H. nazarii and H. gargantua are attributed to it. Hattomys are very large cricetids, and the evolution of the genus is characterized by a considerable increase in size, and an increasing predominance of ridges over cusps. The supposedly oldest Gargano localities yielded, apart from the lineage H. beetsi-nazarii-gargantua, some scarce material of three other hamster species: a Megacricetodon, a Cricetulodon and a Cricetus. Comparison with the Spanish sequences of rodent faunas shows that the Gargano faunas probably are of late Turolian age, equivalent of the Messinian.

Gay ex Laharpe was discovered in the southern part of the country near Reusel in the province of N.-Brabant (ADEMA, 1974) in connection with a record from Belgium, where the species occurs abundantly now in 6 hour-squares (D’HOSE, 1976). In 1974 J. ensifolius Wikstr. was found in the northern part of the country, viz. along the canalized Sleener stream near Emmen in the province of Drente. The discovery of this new rush for the Netherlands does not elucidate the problem of the origin of North American species in Europe.

Cantellius cardenae spec. nov. (Cirripedia: Pyrgomatinae) from Acropora (Isopora) brueggemanni (Brook, 1893) (Anthozoa: Acroporidae), a case of host specificity in a generalist genus
Provedor de dados: 16
Autores: Achituv, Y.; Hoeksema, B.W.
A new species of coral inhabiting barnacle Cantellius cardenae spec. nov. (Crustacea, Cirripedia: Pyrgomatinae) is described. This barnacle was found on the staghorn coral Acropora (Isopora) brueggemanni (Scleractinia: Acroporidae). It is characterized by having transversally elongated scuta and narrow terga with a spur length more than half of the total tergal length. This species belongs to the secundus group of Cantellius, which includes barnacles with transversally elongated scuta, and which are limited to the Acroporidae. The distribution of C. cardenae supports the hypothesis that structurally specialized pyrgomatines occupy a more limited variety of hosts than do morphologicaly generalized ones.

Scarab beetles at the interface of wheel invention in nature and culture?
Provedor de dados: 16
Autores: Scholtz, G.
In this review some examples of rolling behaviour in nature are described and discussed in terms of the realised degree of wheel-like locomotion. The combination of rotation and the use of the low friction resistance of circular and smooth surfaces to transport a heavy load, as is seen in scarab beetles rolling dung pills, is the closest degree of similarity to a wheel found in nature. Populations of dung rolling scarabs may have benefited from the early domestication of large mammals in the Middle East. I suggest that an increased opportunity to observe pill rolling scarab beetles has inspired humans to invent the wheel.

Does biogeography have a future in a globalized world with globalized faunas?
Provedor de dados: 16
Autores: Schram, F.R.
The study of biogeography was once a pillar of evolution science. Both Darwin and especially Wallace found great inspiration from the consideration of animal distributions. However, what is to happen to this discipline in a time of global trade, mass movement of people and goods, and the resulting globalization of the planet’s biota? Can we still hope to delve into the fine points of past geography as it affected animal and plant evolution? Maybe we can, but only with careful study of life forms that suffer minimal affects – at present – from globalization, viz., marginal faunas of quite inaccessible environments. Two examples taken from syncarid crustaceans illustrate this point. Bathynellacea provide insight into ancient patterns of distribution and...

Rijstgras [Leersia oryzoides (L.) Swartz] in het Middennederlandse rivierengebied
Provedor de dados: 16
Autores: Kerkhof, Dick; Duistermaat, Leni (H.).
Leersia oryzoides has declined probably less dramatically than was assumed.² This freatophitic species is easily overlooked because its vegetative parts appear late in summer, and its inflorecences come out of the sheaths in warm summers only. In the region Vijfheerenlanden (province of Zuid-Holland) it is found in 29 kilometer squares in the period 1992—1994. Its occurrence seems to be related to the presence of bare places and steep banks of ditches with a southern exposition, as well as of seepage water. It is likely that its present distribution is larger than presented in Figure 1.

Autores: Galil, B.S.
A study of the genus Leucosia Weber, 1795, led to the establishment of the identity of the type species, L. craniolaris (Linnaeus, 1758), designation of a neotype and redefinition of the genus. Leucosia is now restricted to 4 species: the type species L. craniolaris (Linnaeus, 1758), L. punctata Bell, 1855, L. moresbiensis Haswell, 1880, and a new species, L. rubripalma. They differ from all other species heretofore assigned to the genus in having first male pleopod with a screw-like tightly coiled shaft, terminating in a setose muff. The species are described or redescribed and illustrated, extended synonymies are given, and a key for their identification is provided.

In vitro cultivation of malignant lymphoblasts of transplantable Mouse Lymphosarcoma MB (T 86157) without typical mesenchyme cells
Provedor de dados: 16
Autores: Bruyn, Willemina M. de.
Previous investigations (see Literature) by means of tissue culture methods have shown that the malignant lymphoblasts of mouse lymphosarcoma MB (T 86157) can be cultivated indefinitely when in the presence of actively growing mesenchyme cells. Under the cultural conditions provided, which included the use of low concentrations of embryo extract, a symbiotic relationship appeared to be established between the malignant lymphoblasts and the normal mesenchyme. It was also shown that media rich in embryo extract allowed only fibroblasts to proliferate. In the present article we wish to report some results of observations on the cultivation of the malignant lymphoblasts without the supporting mesenchyme.

Marine localities

Autores: Wagenaar Hummelinck, P.
Some twenty-five years have passed since short descriptions were published of marine and saltpond habitats sampled in the Caribbean during three zoological collecting trips made by the author in 1930, 1936/37 and 1948/49 (these Studies, vol. 4, no. 17, 1953). Sampling of the shallow coastal waters of the Caribbean was continued in 1955, 1963/64, 1967, 1968, 1970 and 1973, during six visits the main purpose of which was not always the study of the marine fauna. Although collecting was done single-handed and rather incidentally, with no other equipment than a knife, fine-meshed nets, formaldehyde and alcohol, the material collected proved to be sufficiently valuable for scientific purposes to justify the publication of a list of the new marine localities.

Een tweede vindplaats van Sphagnum riparium Ångström in Nederland
Provedor de dados: 16
Autores: Schroevers, P.J.; Voo, E.E. van der.
The first record of Sphagnum riparium Angstrom in the Netherlands was made by Meyer in 1946. The present authors mention a new locality of it in the “Peel”, a drained region of raised bog in the southern part of the Netherlands. A description of the material is given and the environment has been analysed. The latter research leads to the following conclusions: 1. S. riparium is found in man-made bog pools, which, originally oligotrophic, by influence of the surroundings have changed into a slightly meso-metatrophic habitat. 2. The species is only found in pools, arranged in more or less extended systems. A light movement of the water may be required. 3. A certain amount of shadow may favour the growth and occurrence of the species.

Autores: Weeda, E.J.
Scapania undulata was recorded on the bank of the Hegebeek in the southeasternmost part of Twente, near the German border. It was first collected there in 1977. Curiously enough, this hepatic was discovered in the Netherlands only as late as 1956, although it is not likely to be a recent immigrant. Sofar records had only been published referring to rivulets on the Veluwe (prov. of Gelderland) and near Hilvarenbeek (S. of Tilburg, prov. of Noord-Brabant). It thrives on woody or stony substrata about the spring water level. Along the Hegebeek, it was found exclusively on Alnus glutinosa-roots uncovered by the stream.

Ancient DNA analysis indicates the first English lions originated from North Africa
Provedor de dados: 16
Autores: Barnett, R.; Yamaguchi, N.; Shapiro, B.; Sabin, R.
The Royal Menagerie of England was established at the Tower of London in the 13th Century and served as a home of exotic  animals until it was closed on behalf of the Duke of Wellington in 1835. Two well-preserved lion skulls recovered from the  moat of the Tower of London were recently radiocarbon-dated to AD 1280-1385 and AD 1420-1480, making them the earliest  confi rmed lion remains in the British Isles since the extinction of the Pleistocene cave lion. Using ancient DNA techniques and  cranio-morphometric analysis, we identify the source of these first English lions to lie in North Africa, where no natural lion population remains today.

The robberfly Stichopogon elegantulus new to the Netherlands (Diptera: Asilidae)   A female of the robberfly Stichopogon elegantulus (Wiedemann in Meigen 1820) was discovered in a malaise trap in Papenvoort (Drenthe, the Netherlands) on June, 22th, 1998. It is the first record for the Netherlands. The capture is odd because it is far north from the nearest sites where the species occurs, along the river Rhine in the southern parts of Germany. In Germany, the species extends its range northward. We expect, however, that the Dutch specimen was transported accidentally by man. There are no populations between our site and the sites in southern Germany, making it improbable that the range already extends so far north.

A divided infraorbital foramen is an important morphological feature in lion taxonomy and has previously been considered to occur only in the Asian lion, Panthera leo persica. Based on an examination of 498 lion skulls from museum collections in Europe and southern Africa, we report for the first time on the prevalence of the divided infraorbital foramen in African lions, as well as its occurrence in the tiger, P. tigris and the extinct Pleistocene European cave lion, P. leo spelaea. The higher frequency of this characteristic in Asian lions may have occurred after the lion colonised Asia, and can be considered an important morphological feature characterising this population. It is not clear whether recent anthropogenic population bottlenecks have...

Fertilizers of various kinds are used for the cultivation of crop plants for hyper production of plant based food materials. The study used bio-molecules made in a bacterial cell. The experimental results showed tremendous effect on plant growth. These cellular molecules were made by treating the bacterial cells with   lysozyme and protenase K. The   wet/weight was increased in multiple folds compared to that of control sets. The fold of increase was 4.79 for rice, 2.77 for wheat, 1.89 for gram and 1.89 for pea when bacterial cellular molecules were used as fertilizer.

Lateral Suspension Systems for Farm Tractors
Provedor de dados: 19
Autores: 箕浦, 邦雄.
本研究は，トラクタ座席における運転者の振動暴露を減少させ， 乗り心地と運転環境を改善する目的で開発した水平方向サスペンションに関する研究である。 既往座席研究については，上下振動を減衰させることに重点がおかれ，水平方向，特に水平左右方向の振動を減衰させることについては，重要視されてこなかった。また，研究や実験時のトラクタ運転姿勢は，進行方向正面を向き，両手でハンドルを保持する姿勢でおこなわれてきた。また，これは実際の運転姿勢を反映しているとは言えず，実状に即していないことが考えられる。 本研究では，トラクタ運転者の作業時における運転姿勢の実態を知るために，各作業中の後方視回数・時間および間隔等を実測・記録した。その結果，運転者は作業中片手でハンドルを保持し，斜め右前方を向いた姿勢で運転していることが分かった。後方視は，播種，移植作業で作業時間の4～7%，防除，収穫作業では30～50%であった。また調査した11種の作業において，平均24 秒に一度後方視し，その継続時間は2秒という頻度であった。この後方視は，防除作業や作畦作業など一部を除き，ほぼすべて右側からおこなわれる。農業者は長年にわたり，右側から後方視をする姿勢を続けたことで，右側から後方視しやすい姿勢で運転し，左側から後方視することは，必要最小限である。このことから，トラクタ座席や操縦装置は，座席の中心にある回転軸を左前方に移動して，座席を右方向に回転した際に，右膝が操作装置などに接触しないようにするなど，無理なく右側から後方視が可能な機能を装備しなければならないことが分かった。...

African Penguins Spheniscus Demersus Along The Kwazulu-Natal Coast, 1981–1999
Provedor de dados: 20
Autores: Whittington, P.A.; Underhill, L.G.; Esmonde-White, D.A.; Wilkinson, C.P.
The African Penguin is rare east of Algoa Bay, Eastern Cape, South Africa. Ninety-nine penguins were found onshore along the coast of KwaZulu-Natal in 1981–1999, mostly in a state of starvation. Of these, 77% were between June and October during, and immediately after, the ‘sardine run’ of Sardine Sardinops sagax; 95% of birds that were aged were first-year birds; 96% were in the southern half of KwaZulu-Natal, south of Mtunzini (29°S) where the sardine run is strongest. The observations suggest that juvenile penguins from the nearest breeding colonies, in Algoa Bay, are drawn eastwards by the migrating Sardines; when these shoals dissipate, a lack of food leads to them coming ashore.

Autores: Irusta, G.; Pérez, M.; Renzi, M.A.; Castrucci, R.
The activity of fishing fleets for hake Merluccius hubbsi south of 41°S Argentine Sea, SW Atlantic, is described. In order to establish the standard group of vessels, density indices derived from research cruises and ice-chilling fleets were related. Group four 1,400-1,800 HP related better to the abundance trend. Also, two series of indices associated to different fractions of the population were estimated: juveniles  age 2) and adults age 3-5. Finally, a total catch per unit effort CPUE for the region south of 41°S, which showed a declining trend during the period considered 1991-1997, was calculated.

What happened to the South Coast El Niño 1997-98, squid catches?
Provedor de dados: 20
Autores: Roberts, M.J.
FROM ALL ACCOUNTS, the intense 1997-98 c impacted most regions in the world shown to be historically sensitive to these events following text-book rules. South Africa appears to be the exception. The original forecast gave a 77% chance of catastrophic drought for the past summer in Southern Africa (Farmers Weekly, April 17 1998). The impact, turned out, was mixed. Three-quarters of South Africa experienced drought while the eastern part had 40% more rain that normal! The South Coast lies between the western winter rainfall region of the country and the eastern summer rainfall region. The question is, what influence did El Niño have on this twix zone, and, in particular, the South Coast based squid fishery?

Isolated embryonic membranes (i.e. the outer cuticular membrane, the fibrous layer, the inner cuticular membrane and the hatching membrane) and homogenates of incubated, decapsulated cysts of 16 populations from five &lt;i&gt;Artemia&lt;/i&gt; species (Crustacea, Anostraca) were examined by sodium dodecyl-sulphate polyacrylamide gel electrophoresis. Characteristic differences in major polypeptides between 45 and 205 kD were seen. These differences might be used as markers for identification of different &lt;i&gt;Artemia&lt;/i&gt; species. The validity of this approach in characterizing &lt;i&gt;Artemia&lt;/i&gt; populations is discussed.

Spatial segregation in copepod species from a brackish water habitat
Provedor de dados: 27
Autores: Heip, C.H.R.; Engels, P.
The segregation along the horizontal space dimension of the niche has been investigated in six copepod species occurring together in a brackish water habitat.All but one species show an aggregated pattern which may be described by a negative binomial distribution. The aggregations are small with a radius of 5-15 cm and are distributed randomly in the habitat. Aggregation of different species do not overlap; niche-overlap in this dimension show a somewhat wider utilization of space by the dominant species and insignificant overlap between species; there was no competition for space at the time of the investigation.

Autores: Ivanova-Peneva, Sonya.
Organic farming is a major policy priority for agriculture in Bulgaria and one of the highlights of the Common Agricultural Policy for the period 2014-2020. Regulations of organic production, and import and export of such products are clearly regulated and aligned with European requirements. Areas under organic conditions and the number of operators involved in the control system are continuously growing. In 2012, there was a significant increase in the area of organic production, reaching 40 378.77 ha. After 2009, in Bulgaria an increase in the number of organic operators and the amount of areas more than four times has been outlined. A considerable increased diversity of organically grown crops and livestock has been observed. Bulgaria has favorable...

Incidence of limiting factors on organic winter wheat performance
Provedor de dados: 21
Autores: Casagrande, Marion; David, Christophe; Valantin-Morison, Muriel; Jeuffroy, Marie-Hélène.
French organic farmers are asked to increase Grain Protein Content (GPC) of organic winter wheat to guarantee the breadmaking quality required from millers. Facing with the recent depletion of organic products, farmers also need to stabilize and increase the yield performance. The aim of our study is to give the explanations of the yield and GPC variability generally observed in organic production. A diagnostic method will be implemented on a network of ca. 10 fields per year during two crop years added with previous field network (77 fields) and experi-ments (4 experiments on cultivars). We will under-stand yield and GPC performance from environmental and agronomic conditions  and relate the observed limiting factors with crop management, climatic...

Autores: Henchion, Maeve; McIntyre, Bridin.
The total organic market is valued at more than €100 million. The fresh and chilled category accounts for the majority of this (€77.3m), followed by ambient (€22.6) with  a very small amount accounted for by the frozen category(€0.7m). Whilst the sector has grown by 82% in the last 2 years (Bord Bia, 2008), there are signs of a slow down  in growth. This paper looks at what is going well from a marketing perspective,identifies some areas requiring attention and suggests a change in positioning to  maintain current levels of growth.

When shifting from traditional ploughing to no-till cultivation there will be new possibilities to weeds. However, the changes in weed population are more dependent on each field than on cultivation method.    We had two field trials in southern Finland (Jokioinen and Mietoinen) on heavy clay for four years (2001-2004). The main treatment was direct seeding or conventional sowing after autumn ploughing combined with spring rotary hoeing.

Most common pests of eucalyptus plants in Brazil are leaf cutting ants and defoliating caterpillars. Other groups, eventually, feeding on eucalyptus include Heteroptera and cicadas. The objectives of this work were to identify and to describe attack symptoms of Cephisus siccifolius (Walker 1851) (Hemiptera: Aphrophoridae) on eucalyptus trees in a stand of 25.77 hectares in the State of Bahia, Brazil, where 99.3% of them were attacked by this spittlebug. Damage was more severe on branches and leaves. Tree death was, relatively, low while those cut showed 4.7 colonies of this spittlebug with 21.9 nymphs per colony. Cultural control with the removal of trees attacked was recommended.

Phototoxic compounds and biological activity of extracts from Eupatorium morifolium Mill. (Asteraceae)
Provedor de dados: 85
Autores: Pérez-Amador,MC; Muñoz Ocotero,V; García Jiménez,F.
Leaves of Eupatorium morifolium Mill. were analyzed for phototoxic compounds, and the toxicity of their hexane extract was evaluated against Bacillus subtilis. The phototoxic compounds were analyzed by TLC. In the plate, pale blue spots indicated the presence of these compounds. This was confirmed by the UV extract spectrum and the antibacterial activity against Bacillus subtilis. The biological activity of the leaf extracts (hexane, ethyl acetate or methanol) was also studied. The antiinflammatory activity was determined using the edema test on mouse ears, and the bactericide activity was assayed against Bacillus subtilis and Escherichia coli. A strong anti-inflammatory activity was shown by the leaf extracts. The ethyl acetate extract exhibited the...

Optimal Institutional Mechanisms for Funding Generic Advertising: An Experimental Analysis
Provedor de dados: 31
Autores: Messer,   Kent D.; Schmit,   Todd M.; Kaiser,   Harry M.
Given the uncertain legal status of generic advertising programs for agricultural commodities, alternative voluntary funding institutions are investigated hat could provide a high level of benefits to producers. This experimental study simulates key economic and psychological factors that affect producer contributions to generic advertising. The results suggests that producer referendum play a critical role in increasing contributions and that producer surplus is maximized by a Provision Point Mechanism instituted by producer referendum with thresholds ranging from 68% to 90%, and expected funding from 47% to 77% of the time, depending on the level of advertising effectiveness.

Do Competition and Ownership Matter? Evidence from Local Public Transport in Europe
Provedor de dados: 31
Autores: Boitani,   Andrea; Nicolini,   Marcella; Scarpa,   Carlo.
This paper investigates how the ownership and the procedure for the selection of firms operating in the local public transport sector affect their productivity. In order to compare different institutional regimes, we carry out a comparative analysis of 72 companies operating in large European cities. This allows us to consider firms selected either through competitive tendering or negotiated procedures. The analysis of the data on 77 European firms over the period 1997-2006 indicates that firms operate under constant returns to scale. Retrieving the residuals we obtain a measure of total factor productivity, which we regress on firm and city characteristics. We find that when firms are totally or partially in public hands their productivity is lower....

Induced Innovation in the High Rainfall Zone
Provedor de dados: 31
Autores: Martin,   John F.
The induced innovation hypothesis states that the direction of technical change is determined by changes in relative input prices acting as a "spur to invention". To determine the validity of this hypothesis for the High Rainfall Zone of the Australian sheep industry, technical change biases for five input categories were measured using time series data for the period 1952-53 to 1976-77. These biases were then related to relative changes in the price of these input categories. The biases were measured by the application of a translog cost function model and suggested that, in general, technical change has been biased toward the saving of labour and land, the using of livestock, and neutral in regard to capital, and possibly materials and services....

EMPIRICAL ANALYSIS OF COST AND RETURNS TO COMMERCIAL TABLE EGG PRODUCTION IN LAGOS STATE
Provedor de dados: 31
Autores: Evbuomwan,   G.O.
Using basic statistics and a simple gross margin analysis procedure, it is apparent that commercial table egg production in Lagos State is profitable. Under the same assumption and based on available statistics, the gross margin for a commercial table egg producer with 1000 laying birds has increased from N975,000:00 in 1998 to N1,050,000:00 in 2005, representing an increase of 7.7 percent. The demand for poultry products is expected to grow in view of increase in per capita income, increased awareness of the health implications of inadequate intake of protein in the human diet and the outbreak of avian influenza in Asia. Thus, increased production of table egg under the Presidential Initiative is sustainable and should be maintained.

Experts and Non-experts
Provedor de dados: 31
Autores: Valsecchi,   Irene.
The paper is concerned with the interaction between two agents: an expert, announcing his probability that a particular state of the world will occur, and a non-expert decision-maker, who takes action according to his posterior beliefs. The decision-maker considers the expert an experiment of uncertain reliability and takes the received messages as the outcomes of such an experiment. The model of the expert in the decision-maker’s mind bears no relation with any measure of the expert’s actual information. The paper shows that messages will be biased, notwithstanding solidarity between the agents. However, the longer the interaction, the less severe will be the bias.

BENEFIT-COST ANALYSIS OF NORTH DAKOTA'S GARRISON DIVERSON UNIT:  A CASE STUDY OF CONFLICTING INTEREST
Provedor de dados: 31
Autores: Pfeiffer,   George H.
Federal agencies are generally required to justify the economic value of proposed water resources development projects with benefit-cost analyses. Responsibility for economic analyses lies principally with the proposing agency, under broad policies and procedures guidelines. The economic evaluation of the Garrison Diversion Unit in North Dakota was used as a case study to examine the ability of federal agencies to evaluate their own projects. A consistent tendency to overestimate project benefits and underestimate project costs was found. Revised benefit-cost ratios ranged from 0.44 to 1 to 0.77 to 1, depending on the discount rate employed.

Harnessing the Forces of Urban Expansion - The Public Economics of Farmland Development Allowance
Provedor de dados: 31
Autores: Chau,   Nancy H.; Zhang,   Weiwen.
For decades, rapid urban expansion has led to concerns over the loss of cultivated land in rural China. This contrasts sharply with another salient feature of the Chinese land policy reform landscape that has gone on largely unnoticed - the addition of newly cultivated land in China through land development has consistently exceeded land conversion. In a model featuring fiscal decentralization, local governments as custodians of land use and development, along with a land development allowance policy instituted in 1998, we show that a land development allowance policy can harness the forces of urban expansion to encourage agricultural land development.

Paying for Safety: Preferences for Mortality Risk Reductions on Alpine Roads
Provedor de dados: 31
Autores: Rheinberger,   Christoph M.
This paper presents a choice experiment, which values reductions in mortality risk on Alpine roads. These roads are on one hand threatened by common road hazards, on the other hand they are also endangered by natural hazards such as avalanches and rockfalls. Drawing on choice data from frequently exposed and barely exposed respondents, we are not only able to estimate the VSL but to explore how the respondents differ in their individual willingness-to-pay depending on personal characteristics. To address heterogeneity in preferences for risk reduction, we use a non-linear conditional logit model with interaction effects. The best estimate of the VSL in the context of fatal accidents on Alpine roads is in the range of €4.9–5.4 million with distinct...

Human Capital Productivity, and Labor Allocation in Rural Pakistan
Provedor de dados: 31
Autores: Fafchamps,   Marcel; Quisumbing,   Agnes R.
This paper investigates whether human capital affects the productivity and labor allocation of rural households in four districts of Pakistan. The investigation shows that households with better-educated males earn higher off-farm income and divert labor resources away from farm activities toward nonfarm work. Education has no significant effect on productivity in crop and livestock production. The effect of human capital on household incomes is partly realized through the reallocation of labor from low-productivity activities to nonfarm work. Female education and nutrition do not affect productivity and labor allocation in any systematic fashion, a finding that is consistent with the marginal role women play in market-oriented activities in Pakistan. As a...

Political Mergers as Coalition Formation
Provedor de dados: 31
Autores: Weese,   Eric.
Political coalition formation games can describe the formation and dissolution of nations, as well as the creation of coalition governments, the establishment of political parties, and other similar phenomena. These games have been studied from a theoretical perspective, but the resulting models have not been used extensively in empirical work. This paper presents a method of estimating political coalition formation models with many-player coalitions, and then illustrates this method by estimating structural coefficients that describe the behaviour of municipalities during a recent set of municipal mergers in Japan. The method enables counterfactual analysis, which in the Japanese case shows that the national government could increase welfare via a...

THE POLITICAL ECONOMY OF FOOD SUBSIDY REFORM IN EGYPT
Provedor de dados: 31
Autores: Gutner,   Tamar L.
Egypt has a large food subsidy program that has created a relatively effective social safety net, but it has also drained budgetary resources and proved to be poorly targeted toward the poor. Discussions about reforming the system to improve its effectiveness have run into extreme political sensitivities surrounding the issue of food subsidies. Egypt, therefore, well illustrates the quandaries that policymakers and others contemplating food subsidy reform face in developing countries. This study examines the political economy of food subsidy reform in Egypt and discusses the economic and political advantages and disadvantages of nine possible reforms. The study concludes that the reforms that have the greatest chance of success are those that reduce the...

The application of spatial models in the analysis of bilateral trade flows: An alternative to the Armington approach for the world sugar market
Provedor de dados: 31
Autores: Nolte,   Stephan.
This paper suggests spatial models as an alternative to the Armington approach to model bilateral trade. While the use of spatial models has been accepted for decades, they are rarely chosen for such analyses. However, problems inherent in the application of the Armington approach can be overcome through the use of spatial models. To demonstrate, a simple spatial model of the world sugar market is built and used to simulate a multilateral liberalization scenario. Additionally, an identical model is constructed, applying the Armington approach. The results of the spatial model of the sugar market are found to be more plausible than those generated by the Armington-based model.

Objective: To estimate welfare maximising tax rates for beer, wine, and spirits using a mathematical model that considers both the welfare loss alcohol taxes impose on non-abusive consumers and the welfare gains due to alcohol taxes reducing externality costs. Results: Optimal per litre of pure alcohol (LAL) tax rates are substantially different to both current alcohol tax rates and the uniform tax rate recommended as part of the 2010 Australian Government Tax Review. Given an individual consumer utility decision model, the best estimate values of the welfare maximising LAL tax rates are: $37 for beer, $11 for wine, $50 for spirits, and $77 for ready-to-drink spirits. Conclusion: As externality costs and the responsiveness of consumers to price changes are...

Analysis of farm household technical efficiency in Northern Ghana using bootstrap DEA
Provedor de dados: 31
Autores: Abatania,   Luke N.; Hailu,   Atakelty; Mugera,   Amin W.
Crop production is the main source of livelihood for households in Northern Ghana. The government is committed to improving crop production and knowledge about the technical efficiency of crop farms is essential in guiding policy decisions. This paper examined the technical efficiency of 189 crop farms in Northern Ghana using data envelopment analysis (DEA) with bootstrapping. We found that bias-corrected average technical efficiency of the sample farms is 77.26%. The estimated scale efficiency is 94.21%. In a second stage regression, we found that hired labour, geographical location of farms, gender and age of head of household significantly affect technical efficiency. Policy implications of the results are discussed.

Leviathan and pure public goods in a federation with mobile populations
Provedor de dados: 31
Autores: Yamaguchi,   Chikara.
This paper investigates properties of the second best allocation in a federation where regional governments provide a pure public good non-cooperatively and policy makers are neither entirely benevolent nor wholly self-serving. A high degree of household mobility across regions forces the governments to raise the efficiency of the public good, however, it also helps to waste resources. It is shown that regional Leviathans not only under-provide the public good but also decrease the amount of wasteful expenditures as households become less mobile. Central government’s intervention can enhance efficiency if households are attached to particular regions.

Autores: Hinson,   Roger A.; Bruchhaus,   Michael N.
Consumers were surveyed to understand preference in an effort to stabilize acreage and market share in a minor strawberry production area. Preferred attributes were identified using conjoint analysis. Local product was highest in overall relative importance, followed by price, pesticide strategy, and container. Cluster analysis identified groups with similar demographics. For two groups, local product was 77 percent and 67 percent of relative importance; for another group, price was about 75 percent of importance; while the final group was balanced across three attributes. Alignment with consumer preferences and with strategies of local retailers and wholesalers lead to suggested tactics to support local product.

Relationship between the Unemployment Rate and the Demand for Orange Juice
Provedor de dados: 31
Autores: Brown,   Mark G.
This study examined the relationship between the unemployment rate and the demand for OJ.  Based on the demand estimates obtained, the hypothesis that unemployment is having a significant negative impact on OJ demand cannot be refuted.  Over the sample period, the unemployment rate increased by about 4.5 points, resulting in a 7.7% to 12.6% decline in OJ demand, based on the alternative model estimates.  The unemployment rate, however, has trended upward in recent years, raising the possible that it may be reflecting to some extent the impact of other trend related factors such as preferences for reduced calories.

Autores: Henning,   Steven A.; Vandeveer,   Lonnie R.; Kennedy,   Gary A.; Green,   Shane.
Rural land comprises 77 percent of Louisiana's total land acreage, with a wide diversity of physical characteristics and use. Therefore, reliable rural real estate market information is expected to be of value to landowners, investors, borrowers, lenders, realtors, appraisers, public taxing authorities, and policy makers.  This report presents the results from the second annual Louisiana Rural Land Market Survey. Results of this study suggest that land values vary by area of the state and the primary commodity grown on the tract. Substantial variation in land value within areas and by parish suggests a number of factors affect rural land values and markets.

The Benefits and Costs of Proliferation of Geographical Labeling for Developing Countries
Provedor de dados: 31
Autores: Anders,   Sven M.; Caswell,   Julie A.
Food product attributes related to geographical origins are a topical issue in global food trade. The provision of geographical labeling may occur through geographical indications under the mandated trade rules of the TRIPS Agreement, through trademarks, or through country-of-origin labeling. The overall effect of the expansion of geographical labeling on developing countries depends on a complex mix of market opportunities that may yield substantial benefits as well as implementation costs. Increasingly, the analysis of this overall effect will need to evaluate the joint impacts of different forms of geographical labeling on the market position of developing countries.

The majority of consumers surveyed (77 percent) report awareness of the Jersey Fresh, state-sponsored promotional program. However, certain segments appear more likely to be familiar with Jersey Fresh and its logos than others are. Behavioral and demographic models were constructed to evaluate which characteristics influence consumer awareness of Jersey Fresh. The results indicate that those who shop at more than one supermarket, those who frequently shop at direct marketing facilities, and those who frequently read food advertisements are more likely to exhibit a preexisting awareness of the Jersey Fresh Program. The results also indicate that the period of residence in the state positively contributed to the awareness of the program.

Fuzzy Quantitative Measure on Brand Extension of Agricultural Products
Provedor de dados: 31
Autores: Chen,   Youxing; Xu,   Hui.
Based on the apprehension of the connotation of brand extension, we select five factors to evaluate the brand extension of agricultural products, including the consumers’ attitude towards original brand of agricultural products, relevance between original products and extensive products, association of agricultural brands, difficulties in making the extensive agricultural products, and cultural compatibility of original brand. We also establish the index system of influencing factors for brand extension of agricultural products, and adopt multi-level measure model to empirically analyze the brands A and B. Result shows that the comprehensive measure values of brands A and B are 77.35 and 78.25, respectively, indicating the extension effect evaluation of...

Provedor de dados: 31
Autores: Dargatz,   David.
The NAHMS Beef '97 Study was designed to provide both participants and the industry with information on the nation's cow-calf population for education and research.  The USDA's National Agricultural Statistics Service (NASS) collaborated with NAHMS to select a statistically-valid sample yielding 2,713 producers from 23 states.  The 23-state target population represented 85.7 percent of U.S. beef cows on January 1, 1997, and 77.6 percent of U.S. beef operations.  NASS enumerators collected data for this report via a questionnaire administered on-farm from December 30, 1996, through February 3, 1997.  Contact for this paper:  David Dargatz

2006 Michigan Cash Grain Farm Business Analysis Summary
Provedor de dados: 31
Autores: Wittenberg,   Eric; Harsh,   Stephen B.
This report summarizes the 2006 financial and production records of 77 Michigan cash grain farms. To be included, the farms must have produced at least 50 percent of gross cash farm income from one or a combination of these items: corn, soybeans, wheat, navy beans, oats, sugar beets and other small grains. The records came from Michigan State University’s TelFarm project and Farm Credit Service of Michigan. The values were pooled into averages for reporting purposes.  Farm records were included if a farm financial analysis had completed 2006 data including beginning and ending balance sheets and a statement of income and expenses. The data was checked to verify that cash discrepancy was less than 10% of gross cash inflow and that debt discrepancy was less...

The Capitalization of Wildlife Recreation Income into Farmland Values
Provedor de dados: 31
Autores: Henderson,   Jason R.; Moore,   Sean.
Wildlife recreation - hunting, fishing, and wildlife watching - appears to be an increasingly important pastime for many Americans. From 1991-2001, U.S. wildlife recreation expenditures surged from $77 billion to $108 billion in 2001 dollars. Land lease and ownership expenditures by wildlife recreation participants are also rising and appear to be capitalized into farmland values. This paper analyzes the impact of hunting lease rates on farmland values in Texas. The results indicate that counties with higher wildlife recreation income streams have higher land values.

Pesticide Use in Vegetable Crops: Frequency, Intensity and Determinant Factors
Provedor de dados: 31
Autores: Jeyanthi,   H.; Kombairaju,   S.
This paper has examined pest management practices in four important vegetable crops, viz. chillies, cauliflower, brinjal and bhendi using farm level cross-sectional data. Average pesticide usage has been estimated at 5.13, 2.77, 4.64 and 3.71 kg active ingredient per hectare on chillies, cauliflower, brinjal and bhendi crops, respectively. On an average, cauliflower and brinjal are each given 15 applications, chillies is given 13 and bhendi is given 12 applications. The study has suggested that for reducing pesticide-use, farmers need to be educated about different nonchemical control methods and should be encouraged to adopt integrated pest management (IPM) practices.

Community Tax Evasion Models: A Stochastic Dominance Test
Provedor de dados: 31
Autores: Gandelman,   Nestor.
In a multi community environment local authorities compete for tax base. When monitoring is imperfect, agents may decide not to pay in their community (evasion), and save the tax difference. The agent decision on where to pay taxes is based on the probability of getting caught, the fine he eventually will have to pay and the time cost of paying in a neighbor community. First, we prove that if the focus of the agents’ decision is the probability of getting caught and the fine, only the richest people evade. If instead, the key ingredient is the time cost of evading, only the poorest cheat. Second, we test the evasion pattern on the Automobile Registration System in Uruguay using two stochastic dominance tests. The evidence favors in this case the hypothesis...

Agri-Environmental Policy: Understanding the Role of Regional Administration
Provedor de dados: 31
Autores: Eggers,   Jorg; Laschewski,   Lutz; Schleyer,   Christian.
With regard to agri-environmental schemes (AES) under Regulation (EC) 1257/99, we suggest that their ineffectiveness, inefficiency, and divers uptake is inherent to the way they are institutionalised in the European CAP framework. Based on experiences of the GRANO research project that initiated two Agri-Environmental Forums in Brandenburg (Germany) to integrate local actors directly into designing and implementing local AES we argue that the process of designing AES can be conceptualised as a complex negotiation process at Laender level. The related institutional settings shape possible outcomes and scheme designs. With only "passive support" for decentralised and participatory approaches yet compulsory complex bureaucratic procedures on part of the EU,...

INPUTS, OUTPUTS AND PRODUCTIVITY CHANGE IN THE AUSTRALIAN SHEEP INDUSTRY
Provedor de dados: 31
Autores: Lawrence,   Denis; McKay,   Lloyd.
Tornqvist quantity indexes of output and input are computed for the period 1952/53 to 1976/77 from Australian Sheep Industry Survey data. The computation includes estimating the annual service flow from durable inputs. Total productivity in the sheep industry is estimated to have increased by 2.9 per cent per annum during this 25-year period. While the ratio of capital employed per unit of labour has increased, materials, services and livestock have been the inputs for which the quantity used has increased most rapidly. On the output side, there has been a move towards greater diversification with both crop and cattle enterprises on 'sheep properties' increasing in relative importance.

ECONOMICS OF WHEAT-FALLOW CROPPING SYSTEMS IN WESTERN NORTH DAKOTA
Provedor de dados: 31
Autores: Johnson,   Roger G.; Ali,   Mir B.
Income and risk aspects of wheat-fallow cropping systems are analyzed in western North Dakota.  A wheat yield trend estimation model based on county yields (1950-77) is developed using independent variables of year, annual precipitation, acres of nonfallowed wheat and a dummy variable for fallow and nonfallow practices.  The year-to-year change in wheat yields on fallowed and nonfallowed land indicates that summer fallow is becoming less desirable economically.  Based on 1980 costs and yields, summer fallow maximizes returns to land at low yields, low wheat prices, and high nitrogen prices.  Income variability is reduced under summer fallow.

Autores: Faria,   Rosane Nunes de; Burnquist,   Heloisa Lee.
The objective of this investigation was to evaluate to what degree technical requirements restrict Brazilian exports, based on a survey applied to 77 firms. The variables represented six types of technical measures that are usually imposed upon exported products. To facilitate the interpretation of the results, factorial analysis was used to reduce the number of variables involved. This allowed the construction of two indicators of the degree of restrictiveness of the technical barriers focused by the study. These were an indicator of requirements of technical specification (ITS) and an indicator for information and label requirements (IIL). Descriptive statistics and paired t test showed that the firms surveyed considered the ITS more restrictive to their...

Autores: Vlastuin,   Chris; Lawrence,   Denis; Quiggin,   John C.
Theoretical, conceptual and estimational issues relevant to economies of size studies are discussed in this paper. Some of the issues discussed are the effects of technological change on the position and shape of the average cost curve over time, the relationship between farm size and relative economic efficiency and frontier versus average estimation techniques. There is also a brief review of various measurement and specification problems.  In addition, empirical estimates of the extent of size economies were derived from a flexible translog production function using ASIS data for the New South Wales Wheat/Sheep Zone for the years 1966-67, 1975-76 and 1976-77. Estimation of the production function revealed that, when the relatively fixed inputs of...

Provedor de dados: 89
Autores: Reis,LS; Oliveira,TC.
The purpose of the study was to evaluate ostrich meat protein quality, as its consumption has significantly increased in the last few years in Brazil. Male Wistar rats were distributed in groupe of six elements. The standard group received a casein-based diet, the control group received a protein-free diet, and the experimental group received ostrich meat diet as protein source. The evaluated biological parameters were protein efficiency ratio (PER), net protein ratio (NPR), net protein utilization (NPU), and true digestibility (TD). There were differences (p&lt;0.05) among treatment groups for all evaluated biological parameters. Mean true digestibility values were 92.12% and 75.77% for casein and ostrich meat, respectively.

Las etnias originarias del archipiélago de Chiloé presentan características culturales que plantean preguntas acerca de su origen como entidad genética independiente y distinta del grupo continental. Al respecto, hemos caracterizado las frecuencias de los cuatro haplogrupos amerindios fundadores del ADN mitocondrial en cuatro poblaciones del archipiélago. El componente aborigen materno de estas poblaciones fue superior al 90 %. El análisis de distancias genéticas sugiere una segregación norte-sur en donde las poblaciones septentrionales aparecen más relacionadas con la etnia continental Huilliche. Aún cuando el análisis de diferenciación interpoblacional y de componentes principales muestran una singularidad en el grupo insular, ésta puede ser interpretada...

Pollination and seed dispersal by lizards: a review
Provedor de dados: 97
Autores: GODÍNEZ-ALVAREZ,HÉCTOR.
This paper reviews the ecological literature published during the last 15 years on pollination and seed dispersal by lizards, in order to determine the possible effects of these animals on plant reproduction. This review is only limited to these years because articles on plant-lizard interactions during this period have used more rigorous experimental approaches than those made previously. All compiled data were analyzed considering the conceptual framework provided by the quantity and quality components of pollination and seed dispersal (i.e., effectiveness), since this information is essential to have an idea of the relative contribution of animals to plant fitness. Results showed that 34 species of lizards feed on nectar and fruits of plants. While...

Physical processes, biotic processes and human activities all act to shape marine ecosystems. Future management of these valuable ecosystems requires an integrative approach that takes into account complicated organismal interactions, oceanographic processes that span large scales of time and space, and how anthropogenic effects interact with the natural environment. The temperate west coasts of North and South America represent a unique opportunity for comparison, as many of the same oceanographic processes, particularly upwelling, occur off both coasts. Additionally, a number of marine ecosystems in both areas have surprising parallels. Here we present an overview of the oceanographic processes that dominate the coastlines, and give examples of...

ABSTRACT The aim of this work was to propose a mathematical model to determine the best combination of the by-products of coffee processing in the production of silage. To this end, 13 treatments were evaluated, resulting from the combination of wet coffee husks (WCH) and dried coffee husks (DCH), both with and without the use of molasses (M) and with or without the use of the inoculant Lactobacillus plantarum (I). From these components, various mixtures were proposed and evaluated, using the technique of simultaneous optimisation of multiple response variables. Silages with the best characteristics were obtained from the use of 76.40% WCH, 18.77% DCH, 4.83% of M and 0.0001% I.

This catalogue contains information about the type material of the suborder Heteroptera housed at the Entomological Collection of the Instituto Fundación Miguel Lillo (IFML-Tucumán, Argentina). We listed 60 holotypes and 453 paratypes belonging to 20 families, and three species and one subspecies that were not found in the collection but, according the original description, should be deposited in IFML. Finally, we listed 15 species that are labeled and coded as types but that are no part of the original type series. Nevertheless, they were included in this contribution because the associated information could be useful for future taxonomic research.

Aspectos do problema das cáries dentárias no Estado do Amazonas
Provedor de dados: 36
Autores: Shrimpton,Roger; Giugliano,Rodolfo.
Resumo São apresentados dados sobre a incidência de cáries em 193 crianças pobres de 1 a 8 anos de idade em Manaus, Amazonas, 1976. A incidência de cáries foi de 77,7%, sendo que no grupo etário de 8 anos atingiu a 97,9%. Possíveis fatores locais envolvidos na evolução das cáries e as possíveis medidas a serem tomadas são discutidos. São enfatizadas a inapropriedade do tratamento dentário conservador e a essencialidade de medidas preventivas nesta área tão grande mas esparsamente povoada. A promoção da amamentação sobre a alimentação artificial nas primeiras semanas de vida da criança e a fluoretação do sal, são sugeridas como medidas práticas de mínimo custo e máximo alcance na redução das cáries em populações rurais e urbanas da Bacia Amazônica.

Provedor de dados: 113
Autores: Vargas,Robinson; Chapman,Bruce; Penman,David R.
The effects of temperature, host plant, active ingredient mobility, surfactant, residue age and larval age on the response of Tetranychus urticae Koch to thuringiensin were evaluated in laboratory bioassays. T. urticae larvae were significantly more susceptible to thuringiensin at 13°C than at 28°C. A significantly different response of T. urticae larvae to thuringiensin residues was found on peach and apple leaves. Older T. urticae larvae were significantly more susceptible than younger larvae when exposed to thuringiensin residues. No systemic or translaminar effects of thuringiensin were detected; the leaf surface (upper or lower) and the addition of Silwet L-77 surfactant did not affect the efficacy of thuringiensin. The use of thuringiensin in spider...

Autores: Mazali,Italo O.; Alves,Oswaldo L.
High fidelity calcium carbonate and hydroxyapatite (bio) inorganic replicas of the fibrous network of the dried fruit of Luffa cylindrica are described, utilizing a facile synthetic route. The loofa sponge is a highly complex macroscopic architectural template, an inexpensive and sustainable resource. In the context of the morphosynthesis, the capability of replication of the loofa sponge opens the possibility of the use of biodiversity in obtaining new materials. We would like to emphasize that the template proposed in this paper, makes possible the preparation of inorganic replicas with a very desirable size, on the centimeter scale. This fact is innovative with respect to inorganic replicas described in the literature, which predominate at the...

Vaccines based on the cell surface carbohydrates of pathogenic bacteria
Provedor de dados: 42
Autores: Jones,Christopher.
Glycoconjugate vaccines, in which a cell surface carbohydrate from a micro-organism is covalently attached to an appropriate carrier protein are proving to be the most effective means to generate protective immune responses to prevent a wide range of diseases. The technology appears to be generic and applicable to a wide range of pathogens, as long as antibodies against surface carbohydrates help protect against infection. Three such vaccines, against Haemophilus influenzae type b, Neisseria meningitidis Group C and seven serotypes of Streptococcus pneumoniae, have already been licensed and many others are in development. This article discusses the rationale for the development and use of glycoconjugate vaccines, the mechanisms by which they elicit T...

An overview of chagasic cardiomyopathy: pathogenic importance of oxidative stress
Provedor de dados: 42
Autores: Zacks,Michele A.; Wen,Jian-Jun; Vyatkina,Galina; Bhatia,Vandanajay; Garg,Nisha.
There is growing evidence to suggest that chagasic myocardia are exposed to sustained oxidative stress-induced injuries that may contribute to disease progression. Pathogen invasion- and replication-mediated cellular injuries and immune-mediated cytotoxic reactions are the common source of reactive oxygen species (ROS) in infectious etiologies. However, our understanding of the source and role of oxidative stress in chagasic cardiomyopathy (CCM) remains incomplete. In this review, we discuss the evidence for increased oxidative stress in chagasic disease, with emphasis on mitochondrial abnormalities, electron transport chain dysfunction and its role in sustaining oxidative stress in myocardium. We discuss the literature reporting the consequences of...

SHRIMP U-Pb zircon dating of Pedras Grandes Suite, southern Santa Catarina State, Brazil
Provedor de dados: 42
Autores: Jelinek,Andréa R.; Bastos-Neto,Artur C.; Leite,Jayme A.D.; Hartmann,Léo A.; McNaughton,Neal J.
Two major magmatic pulses of the granitic Florianópolis Batholith in Santa Catarina State, southern Brazil, occurred between 613±5Ma and 595±5 Ma, during the Neoproterozoic Brasiliano Cycle. These ages were obtained by U-Pb isotopic determinations with the sensitive high mass-resolution ion microprobe on igneous zircons from Pedras Grandes Suite in Santa Catarina State. Euhedral zircons remained unaltered close to a fluorite vein deposited at 180?C or more. These ages suggest a northern limit for the Pedras Grandes Suite, explaining the spatial relationship between the fluorite veins and the source rock.

Invariants of germs of analytic differential equations in the complex plane
Provedor de dados: 42
Autores: Câmara,Leonardo M.
We study the classification of germs of differential equations in the complex plane giving a complete set of analytic invariants determining the analytic type of the underlying foliation. In particular we answer in affirmative a conjecture of S. Voronin, and generalize some previous results about dicritical singularities in a straightforward manner. Such problem has its origins in a conjecture proposed by R. Thom in the mid-1970s.

Haematophagous arthropod saliva and host defense system: a tale of tear and blood
Provedor de dados: 42
Autores: Andrade,Bruno B.; Teixeira,Clarissa R.; Barral,Aldina; Barral-Netto,Manoel.
The saliva from blood-feeding arthropod vectors is enriched with molecules that display diverse functions that mediate a successful blood meal. They function not only as weapons against host's haemostatic, inflammatory and immune responses but also as important tools to pathogen establishment. Parasites, virus and bacteria taking advantage of vectors' armament have adapted to facilitate their entry in the host. Today, many salivary molecules have been identified and characterized as new targets to the development of future vaccines. Here we focus on current information on vector's saliva and the molecules responsible to modify host's hemostasis and immune response, also regarding their role in disease transmission.

Embedded positive constant r-mean curvature hypersurfaces in Mm × R
Provedor de dados: 42
Autores: Cheng,Xu; Rosenberg,Harold.
Let M be an m-dimensional Riemannian manifold with sectional curvature bounded from below. We consider hypersurfaces in the (m + 1)-dimensional product manifold M × R with positive constant r-mean curvature. We obtain height estimates of certain compact vertical graphs in M × R with boundary in M × {0}. We apply this to obtain topological obstructions for the existence of some hypersurfaces. We also discuss the rotational symmetry of some embedded complete surfaces in S² × R of positive constant 2-mean curvature.

This study describes the isolation and identification of apigenin-7-O-ghicopyranoside, a flavonoid isolated from the flowers of Bellis perennis L., Asteraceae, an species with a broad spectrum of biological activities. The in vitro antioxidant activity and the inhibition of the enzyme acetylcholinesterase were evaluated. The flavonoid showed strong in vitro antioxidant potential, because of the capacity of removal of hydroxyl radicals and nitric oxide, and also prevented the formation of thiobarbituric acid-reactive substances. These parameters were inhibited at the highest concentration of ApG at rates of 77.7%, 72% and 73.4%, respectively, in addition to inhibiting acetylcholinesterase, suggesting potential use in the treatment of neurodegenerative...

Autores: Magenta,Mara Angelina Galvão; Nunes,Alessandra De Deus; Mendonça,Cláudia Barbieri Ferreira; Gonçalves-Esteves,Vânia.
With the aim of improving inter-specific delimitation of the genus Viguiera Kunth in Brazil, a palynological analysis was undertaken with 27 taxa, representing around 77% of all occurring species. Samples were obtained from herbarium specimens and the pollen grains were analyzed through light and scanning electron microscopy. Characteristics, including the shape of the pollen grains, polar and equatorial diameter, aperture measurements, surface ornamentation and exine thickness, were registered and compared. The pollen grains were medium-sized (25 - 50 mm), isopolar and oblate spheroidal (prolate spheroidal in V. aspilioides Baker). The observed values corroborated the synonymity of some species and also highlighted certain micro-morphological differences,...

Autores: Silveira,Gastão Moraes da; Kurachi,Sergio Augusto Hiroaki; Fujiwara,Mamor.
O controle de ervas daninhas em cafezal cultivado em latossolo roxo, por meio de métodos mecânicos (grade de discos, enxada rotativa, roçadeira) e químico (herbicida), é comparado com a capina manual. Cada implemento foi sistematicamente usado durante o período das águas. Quanto à produção, após dez anos, não houve diferença estatística entre os tratamentos, a não ser no biênio 1976/77, quando a grade e a enxada rotativa tiveram melhor comportamento, não diferindo do herbicida. Observaram-se sinais de erosão superficial provocada por grade de discos, enxada rotativa e herbicida.

Pelletization of seeds of Raphanus sativus L. cv. Redondo Gigante with graphite for germination under water stress conditions
Provedor de dados: 52
Autores: Freitas,Nobel Penteado; Takaki,Massanori.
The effect of water stress on germination of radish seeds is dependent on the presence of light. The effect of pelletization of radish seeds with powdered graphite on the tolerance to water stress under light was analysed. White light and far-red lights were filtered by graphite increasing slightly the tolerance of pelleted seeds to water stress of -0.77MPa. Although red light also inhibited seed germination the graphite had no effect. We propose the pelletization of seeds of Raphanus sativus, at least in cv redondo gigante with graphite as a pratice before planting to increase the tolerance to water stress.

Autores: Martins,A.M.C.; Nobre,A.C.L.; Almeida,A.C.; Bezerra,G.; Lima,A.A.M.; Fonteles,M.C.; Monteiro,H.S.A.
Because thalidomide and pentoxifylline inhibit the synthesis and release of tumor necrosis factor-alpha (TNF-alpha), we determined the effect of these drugs on the renal damage induced by supernatants of macrophages activated with Crotalus durissus cascavella venom in order to identify the role of TNF-alpha in the process. Rat peritoneal macrophages were collected with RPMI medium and stimulated in vitro with C.d. cascavella venom (10 µg/ml) in the absence and presence of thalidomide (15 µM) or pentoxifylline (500 µM) for 1 h and washed and kept in culture for 2 h. Supernatant (1 ml) was tested on an isolated perfused rat kidney (N = 6 for each group). The first 30 min of each experiment were used as control. The supernatant was added to the perfusion...

Desde hace algo más de dos años a la fecha, se viene desarrollando en un sector de la ciudad de Quito, un hecho significativo para la aprehensón de la dinámica de la vida social urbana: la apropiación de los muros citadinos mediante pintas graffitti. La bibliografía sobre el graffitti no es abundante, y no profundiza en una interpretación relacional entre el graffitti y los sujetos de la experiencia. El cuestionamiento, entonces, que cruza este trabajo y que informa la especifidad de los que de él se derivan es el ¿por qué el hecho de desarrollo en Quito y en el tiempo?.

El tema de la descentralización en Ecuador es materia de varios debates, análisis y medidas. La discusión está signada por análisis políticos y jurídicos, y los análisis económicos han sido relativamente limitados. El abordaje económico del tema, por otro lado, es fundamentalmente un asunto de economía política, en tanto incorpora fuertes disputas entre las clases dominantes del país que, entre otros aspectos, tienen que ver con su reproducción económica hoy más restringida y competitiva a escala no solo local, sino nacional y global. De por medio, hay un manejo discursivo que ayuda a construir imaginarios falsos, sobre una reinvindicada descentralización de casi todo y todos.

De acuerdo al psicoanálisis, un aspecto constitutivo del sujeto es el lenguaje, que establece entre el ser humano y su entorno una brecha, mediante la intermediación de representaciones mentales conceptuales surgidas de sus vínculos maternos y paternos. Pero el sujeto aprende a romper los amarres y ataduras impuestas por las conductas, normas y reglas de su cultura. De allí que su posibilidad de crecimiento como sujeto ocurre con su capacidad imaginativa y su aptitud para recrearse un universo simbólico.

Provedor de dados: 122
Autores: Sánchez Parga, José.
Una nueva economía política en la actual sociedad de mercado transforma las luchas del conocimiento, cuando el poder de éstos se encuentra investido y sometido por los conocimientos del poder, y cuando (igual que la circulación de mercancías y capitales) es su circulación social la que más contribuye a la plusvalía de los conocimientos. Tales procesos no sólo cambian epistemológicamente los conocimientos en discursos y su régimen de dominación social sino también la misma politicidad del pensar crítico. Este pensamiento se hace teoría crítica de la sociedad, cuando critica las condiciones socio-económicas y políticas de la producción de discursos.

Sobre la reconstitución del pensamiento crítico (Tema central)
Provedor de dados: 122
Autores: Hinkelammert, Franz J.
La reconstitución del pensamiento crítico pasa por una nueva lectura de los textos clásicos de Marx de crítica a la economía política. No se trata solamente de cuestionar aquellos vínculos entre economía y política sino de enjuiciar el mito del progreso, proponiendo una nueva perspectiva que asuma alternativas de carácter abierto y no concluidas ni cerradas, reconsiderando la dimensión de los proyectos utópicos.

Entre el spray y la pared. Graffiti : liminalidad en el espacio urbano
Provedor de dados: 122
Autores: Ensignia, Marco A.
Desde hace algo más de dos años a la fecha, se viene desarrollando en un sector de la ciudad de Quito, un hecho significativo para la aprehensón de la dinámica de la vida social urbana: la apropiación de los muros citadinos mediante pintas graffitti. La bibliografía sobre el graffitti no es abundante, y no profundiza en una interpretación relacional entre el graffitti y los sujetos de la experiencia. El cuestionamiento, entonces, que cruza este trabajo y que informa la especifidad de los que de él se derivan es el ¿por qué el hecho de desarrollo en Quito y en el tiempo?.

Diversidad de las estrategias campesinas en la provincia del Azuay : un punto de vista geográfico (Debate agrario-rural)
Provedor de dados: 122
Autores: Rebaï, Nasser.
En los Andes ecuatorianos, la migración constituye actualmente la dinámica más importante en el origen de las recomposiciones del medio rural. Si en primer lugar participa en la desestructuración de los hogares campesinos, en retorno, provoca nuevas dinámicas agrarias en los espacios de salida. Se propone mostrar los efectos concretos de la migración en la parroquia Octavio Cordero Palacios, ubicada en la provincia del Azuay, con una mirada más orientada sobre la reorganización del trabajo agrícola y los conflictos campesinos respecto a la tenencia de la tierra.

Ecuador : entre la ilusión y la maldición del petróleo (Tema Central).
Provedor de dados: 122
Autores: Acosta, Alberto.
El ingreso del Ecuador, como productor petrolero de importancia, ocurrida en la década de los setenta del siglo XX, se constituyó en una fuente de financiamiento a tras de la cual se intentaron reformas y modernizaciones del Estado, en particular la fallida política de sustitución de importaciones. Con el decaimiento de los precios, el agresivo endeudamiento y los ajustes forzados para su pago, el petróleo dejó de ser un motor de la economía para convertirse en el “sujeto de pago” de la deuda. Su actual explotación acarrea, además, serios riesgos para la frágil ecología amazónica.

Machado-Joseph disease (MJD) is an autosomal dominant, late-onset neurological disorder and the most common form of spinocerebellar ataxia (SCA) worldwide. Diagnostic genetic testing is available to detect the disease-causing mutation by direct sizing of the CAG repeat tract in the ataxin 3 gene. Presymptomatic testing (PST) can be used to identify persons at risk of developing the disease. Genetic counseling provides patients with information about the disease, genetic risks, PST, and the decision-making process. In this study, we present the protocol used in PST for MJD and the relevant observations from two centers: Brazil (Porto Alegre) and Portugal (Porto). We provide a case report that illustrates the significant ethical and psychological issues...

Queimadas na colheita da cana-de-açúcar: impactos ambientais, sociais e econômicos.
Provedor de dados: 14
Autores: RONQUIM, C. C.
Atualmente a cultura da cana-de-açúcar no Brasil ocupa mais de oito milhões de hectares e faz do País o maior produtor mundial de cana e seus derivados. Nesse contexto, a região Centro-Sul responde por cerca de 90% da produção total. O Estado de São Paulo, maior produtor, vem buscando viabilizar a sustentabilidade desse agronegócio por meio de um protocolo de intenções, regido por lei, em que a prática da queima da palha da cana deve ser gradativamente reduzida até sua completa eliminação. A completa adoção da colheita mecanizada da cana-de-açúcar possibilitará maior ganho ambiental e resultará em menor emissão de poluentes atmosféricos e gases de efeito estufa, na melhoria da qualidade do solo, entre tantos outros ganhos. Ao deixar de queimar a palha da...

Since 1973, spat collection bas been conducted by IFREMER in the bay of Brest. This collection aimed at providing juveniles of Pecten maximus (1973-77) and then Chlamys varia(1977-87) in order to improve the management of the fishing grounds of the two species.  Since 1982, the efforts have been focussed on the P. maximus spat production through the hatchery/nursery systems and the intermediate culture. Juveniles are seeded above a minimum size to create an additional population. In parallel, the levels of spat yied/collector have been followed as a pre-recruit index.  At present time, there is no increase of spat collection during 1985-1990. Moreover, the results rise up the question of water quality in the bay of Brest for this group apparently very...

Atmospheric patterns driving Holocene productivity in the Alboran Sea (Western Mediterranean): A multiproxy approach
Provedor de dados: 5
Autores: Ausin, Blanca; Flores, Jose A.; Sierro, Francisco J.; Cacho, Isabel; Hernandez-almeida, Ivan; Martrat, Belen; Grimalt, Joan O.
High-resolution paleoproductivity variations have been reconstructed in a productive cell in the Alboran Sea for the Holocene. Fossil coccolithophore assemblages have been studied along with the U37 k' -estimated sea-surface temperature ( SST) and other paleoenvironmental proxies. The appearance of this cell is suggested at 7.7 ka cal. BP and was linked to the establishment of the western anti-cyclonic gyre. From that time until the present, the nannofossil accumulation rate of Florisphaera profunda has revealed successive episodes of weakening and strengthening of upwelling conditions in the Alboran Sea that have been simultaneous to changes in Western Mediterranean Deep Water ( WMDW) formation in the Gulf of Lions. A two-phase scenario operating at...

Nitrate respiration and nitrification in estuarine sediments.
Provedor de dados: 5
Autores: Herbert, R.
Seasonal data and depth profiles using super(15)N-labelled NO sub(3)u- show that denitrification (77-90% of NO sub(3)u- respired) rather than NO sub(3)u- dissimilation to NH sub(4)u+ was the principal route of nitrate reduction in Kingoodie Bay sediments. Populations of both groups of NO sub(3)u- reducing bacteria were highest in the 0-20 mm horizon in those sediments where highest rates of NO sub(3)u- respiration were recorded (28.56 mu g N.d super(-1) dry wt. sediment super(-1)). Autotrophic nitrification rates shared a marked seasonality with highest rates (0.92 mu g N.d super(-1).g dry wt. sediment super(-1)) occurring during the summer. Maximum populations of autotrophic nitrifying bacteria were also found in the 0-20 mm sediment horizon and these...

Provedor de dados: 77
Autores: Motta,Victor F; Aguila,Marcia B; Mandarim-de-Lacerda,Carlos A.
The study aimed to evaluate the impact of high-intensity interval training (HIIT) on adipose tissue, pancreatic islets and liver in mice fed high-fat diet. C57BL/6 male mice were fed one of two diets: standard chow (Lean group - LE) or a high-fat diet (Obese group ­ OB). After the first 12-weeks, the animals were divided into non-trained (LE-NT and OB-NT), trained groups (LE-T and OB-T), and started the exercise protocol. The HIIT protocol in the trained animals (LE-T and OB-T) compared to their counterparts (LE-NT and OB-NT) led to a reduction in size of the pancreatic islets (LE-T vs. LE-NT -40 %, OB-T vs. OB-NT -22 %) and to an increase in insulin immunodensity in pancreatic islet (LE-T vs. LE-NT +35 %, OB-T vs. OB-NT +31 %). Apart from the above...

The objectives of this study were to choose an effective embryo reconstruction method and an effective post-activation agent for in vitro production of sei whale (Balaenoptera borealis) interspecies somatic cell nuclear transfer (iSCNT) embryos. Moreover, trichostatin A (TSA) treatment of whale iSCNT embryos was performed to improve the in vitro embryo development. In Experiment 1, the fusion rate was significantly higher (88.1%) in embryos reconstructed using the intracytoplasmic cell injection method (ICI) than that (48.7%) in the subzonal cell insertion (SUZI) counterpart. The rates of pseudopronucleus (PPN) formation (77.4 vs. 77.2%) and cleavage (24.5 vs. 37.0%) did not vary between ICI and SUZI. However, the PPN formation and cleavage rates were...

Most anesthetics have an immuno-suppressive effect on cellular and neurohumoral immunity, and research shows that total intravenous anesthesia (TIVA) with propofol has a greater immuno-protective effect than inhalational anesthesia in human medicine. However, in veterinary clinics, these effects remain ambiguous. To clarify the details, we focused on propofol and isoflurane, investigating clinical blood hematology and immunological profiles drawn from healthy dogs under and after two anesthesia techniques. Twelve healthy adult beagles were included in this study, randomly assigned to the propofol anesthesia group (group P: n=6) or the isoflurane anesthesia group (group I: n=6). In both groups, the number of lymphocytes in peripheral blood decreased after 2...

Several agro-ecological practices have been developed to increase the range of soil fertility management options available to farmers, but little information is available on their labour input requirement and profitability relative to conventional practices. This study used a multiple visit cost-route method to estimate labour inputs and financial profitability of agroforestry-based and conventional (with and without fertiliser) soil fertility management practices in eastern Zambia. Results show that aggregated over a five-year cycle, labour inputs used under agroforestry practices were lower than fertilised maize fields but higher than non-fertilised continuous cropped maize. Agroforestry practices were more profitable (NPV ranging between $233 and $327...

Autores: Salomão,Luiz Carlos Chamhum; Siqueira,Dalmo Lopes de; Pereira,Marcio Eduardo Canto.
Estudou-se o desenvolvimento do fruto da lichieira (Litchi chinensis Sonn.) 'Bengal'. Realizaram-se amostragens semanais, com início aos 35 dias após a antese e término no início da senescência dos frutos. A partir do 77º dia após a antese, os frutos foram decompostos em pericarpo, semente e arilo. A antese ocorreu na primeira semana de setembro. Foram ajustados modelos sigmoidais simples para acúmulo de matéria seca, comprimento e diâmetro. Para o acúmulo de matéria seca, uma fase inicial, de crescimento lento, prolongou-se até o 63º dia após a antese e coincidiu com um período de intensa queda natural de frutos. Do 63º ao 98º dia após a antese, houve uma fase de rápido acúmulo de matéria seca. Até o 77º dia, pericarpo e semente foram os principais...

To investigate the origin and diversity of domestic guinea-pigs Cavia porcellus (Linnaeus, 1758; Rodentia, Caviidae), we sequenced the mitochondrial cytochrome b gene of 12 domestic and 10 wild specimens from six species, including the two presumed as ancestral to the domestic one: Cavia tschudii and Cavia aperea. All maximum parsimony and maximum likelihood analyses grouped C. porcellus with C. tschudii (mean K2P distance = 3.2 %); best trees had 609 steps (CI = 0.796; Bremer support Index (SI) = 28), and a _Ln = 4419.52, with 100 % and 97 % bootstrap support respectively. This clade, supported by three substitutions and 96 % bootstrap, is also obtained in the cladistic analysis of corresponding amino acids. When the C. aperea node was forced to join C....

Under current conditions, large areas of temperate western North America and temperate southern South America have arid to subhumid climates that make them vulnerable to changes as a result of human-induced climate change. Predictions of climate change from global circulation models with a doubling of present atmospheric levels of CO2 suggest large changes in mean annual temperature and small to no changes in mean annual precipitation and the proportion of precipitation received during the summer. Our objective here was to evaluate how predictions of climate change from global circulation models will influence climatic patterns and by inference the distribution of temperate zone ecosystems in North and South America. Calculations of annual water deficits...

Sanitary profile in mice and rat colonies in laboratory animal houses in Minas Gerais: I - Endo and ectoparasites
Provedor de dados: 45
Autores: Bicalho,K.A.; Araújo,F.T.M.; Rocha,R.S.; Carvalho,O.S.
The sanitary conditions of 13 animal houses in nine public institutions in Minas Gerais, and the presence of endo and ectoparasites of mice and rats colonies kept in these facilities were evaluated. Data about barriers to prevent the transmission of diseases and a program of sanitary monitoring were obtained through a questionnaire and local visit. Parasitological methods were performed for diagnosing mite, lice, helminthes, and protozoa parasites in 344 mice and 111 rats. Data have shown that the majority of the animal houses had neither proper physical environment nor protection barriers to prevent the transmission of infections. Parasitological results have shown that only one animal house (7.7%) had parasite free animals, whereas the others have...

Hepatitis C virus (HCV) infection is a serious public health problem, since 80% to 85% of HCV carriers develop a persistent infection that can progress into liver cirrhosis and hepatocarcinoma. Considering that the response of hepatitis C patients to combination therapy with interferon and ribavirin depends on HCV characteristics as well as on host features, we made a retrospective analysis of demographic and anthropometrical data and HCV genotype distribution of chronic hepatitis C patients treated in public and private reference centers in Brazil. The medical records of 4,996 patients were reviewed, 81% from public and 19% from private institutions. Patients' median age was 46 years, and there was a higher prevalence of male (62%) and white patients...

Social condition affects hormone secretion and exploratory behavior in rats
Provedor de dados: 56
Autores: Genaro,G.; Schmidek,W.R.; Franci,C.R.
Studies of behavior, endocrinology and physiology have described experiments in which animals housed in groups or in isolation were normally tested individually. The isolation of the animal from its group for testing is perhaps the most common situation used today in experimental procedures, i.e., there is no consideration of the acute stress which occurs when the animal is submitted to a situation different from that it is normally accustomed to, i.e., group living. In the present study, we used 90 male 120-day-old rats (Rattus norvegicus) divided into 5 groups of 18 animals, which were housed 3 per cage, in a total of 6 cages. The animals were tested individually or with their groups for exploratory behavior. Hormones were determined by radioimmunoassay...

Thromboelastography (TEG®) provides a functional evaluation of coagulation. It has characteristics of an ideal coagulation test for trauma, but is not frequently used, partially due to lack of both standardized techniques and normal values. We determined normal values for our population, compared them to those of the manufacturer and evaluated the effect of gender, age, blood type, and ethnicity. The technique was standardized using citrated blood, kaolin and was performed on a Haemoscope 5000 device. Volunteers were interviewed and excluded if pregnant, on anticoagulants or having a bleeding disorder. The TEG® parameters analyzed were R, K, α, MA, LY30, and coagulation index. All volunteers outside the manufacturer’s normal range underwent extensive...

Autores: Pires Neto,R.J.; Colares,J.K.B.; Fonseca,B.A.L.
The availability of HIV-1 genotype resistance testing (GRT) to clinicians has been insufficiently studied outside randomized clinical trials. The present study evaluated the outcome of salvage antiretroviral therapy (ART) recommended by an expert physician based on GRT in a non-clinical trial setting in Ribeirão Preto, Brazil. A prospective, open, nonrandomized study evaluating easy access to GRT at six Brazilian AIDS Clinics was carried out. This cooperative study analyzed the efficacy of treatment recommended to patients whose salvage ART was guided by GRT with that of treatment with ART based only on previous ART history. A total of 112 patients with ART failure were included in the study, and 77 of them were submitted to GRT. The median CD4 cell count...

Given the causal relationship between specific types of HPV with cervical cancer and precursor lesions, it is important to identify the viral type involved. The aim of this study is to access the prevalence of HPV types in HIV seropositive and seronegative women. Accordingly, 77 HPV positive cervical samples were obtained from 284 women (seropositive (n=112) and seronegative (n=172) for HIV) who attended a Sexually Transmitted Infection clinic, in Vitoria, Southeastern Brazil. Viral DNA was amplified by PCR using MY09/MY11 degenerated primers and the genotyping was performed by Restriction Fragment Length Polymorphism. Seventy five out of the 77 HPV samples were genotyped: 6, 11, 13, 16, 18, 26, 31, 31b, 32, 33, 34, 35, 52, 53, 55, 56, 58, 59, 61, 62, 64,...

Abstract Three dog shelters in Rio Grande do Sul were investigated for associations between the occurrence of respiratory viruses and shelter environmental conditions. Nasal secretions randomly collected during the cold season were tested via PCR, and this data collection was followed by nucleotide sequencing of the amplicons. In shelter #1 (poor sanitary and nutritional conditions, high animal density and constant contact between dogs), 78% (58/74) of the nasal samples were positive, 35% (26/74) of which were in single infections and 44% (32/74) of which were in coinfections. Shelters #2 and #3 had satisfactory sanitary and nutritional conditions, outdoors exercise areas (#2) and animal clustering by groups (#3). In shelter #2, 9% (3/35) of the samples...

Este artículo pretende esbozar tanto los resbalones de la historia, como los abruptos levantamientos que en forma de ruptura generacional, llevaron a la nueva izquierda a gobernar América Latina. Si algo aprendimos de aquellos vientos llamados de izquierda, que sonaban a imposición, dogma, opresión o coerción, es que la verdadera, la coqueta, la frívola y a la vez la sensata izquierda es eminentemente liberadora, solidaria, igualitaria, pero sobretodo colorida, diversa, inmensamente feliz.

Como mejorar el acceso a servicios de salud maternos infantiles en el Ecuador
Provedor de dados: 122
Autores: Méndez de la Torre, Juan Carlos.
Los conceptos de desarrollo en economía han estado mayormente relacionados a las teorías de crecimiento económico, las mismas que se desenvuelven en el margen de conceptos como producción, PIB, capital y acumulación eficiente de bienes y servicios, dejando de lado al beneficiario y el ambiente en el que se desenvuelve la teoría. Desde esta perspectiva, el sector social no representa una variable altamente significativa en los modelos tradicionales de crecimiento económico, sino más bien, se introduce en teorías de crecimiento con capital humano, haciendo referencia principalmente a la inversión en educación y su aporte a la mano de obra como factor de producción. El caso ecuatoriano, aunque denota una tendencia creciente en la inversión social, sobre todo...

Definiciones divergentes de la estrategia de visibilidad en el movimiento LGTB cordobés (Dossier)
Provedor de dados: 122
Autores: Iosa, Tomás; Rabbia, Hugo H.
El presente artículo explora la visibilidad como problema, objetivo y estrategia del activismo LGTB. Enfocado en la reciente apropiación de la Marcha del Orgullo como práctica política por parte de un sector del movimiento LGTB cordobés, se indaga cómo los activistas disputan modos legítimos de articular una estrategia de visibilidad. Signada por el riesgo de su posible mercantilización y el vaciamiento político, la marcha constituyó no obstante el escenario de nuevas y confrontadas definiciones del status ciudadano de la diversidad sexo-genérica. A partir de observaciones de campo y entrevistas a activistas se interrogó cómo la trayectoria en la militancia, las subjetividades exo-genéricas en juego, el acceso diferencial a recursos y la radicalidad...

A pesquisa de Salmonella em carcaças de aves tem mostrado resultados discrepantes, dependendo se as amostras foram colhidas ainda na indústria, imediatamente após o chiller ou no comércio varejista, quando se encontram submetidas à refrigeração por vários dias. Técnicas mais sensíveis, tais como a Reação em Cadeia pela Polimerase (PCR), podem fornecer dados importantes sobre o efeito do resfriamento sobre as células do patógeno, comparando seus resultados com os da metodologia microbiológica convencional (MC). Foram colhidas 130 carcaças de frango, sendo que 65 foram obtidas ainda na indústria (pós-chiller) e imediatamente analisadas e 65 carcaças embaladas e estocadas a 5°C por 72 horas (simulando o varejo), sendo então realizada a pesquisa do patógeno...

Исследованы пищевой спектр и суточный рацион медузы Aurelia aurita L. в северо-западной части Чёрного моря в октябре 2010 г. На шельфе в пище медузы преобладали одноклеточные водоросли (32 %), копеподы (24 %) и хетогнаты (20 %), в глубинной части моря – копеподы ~77 %). При биомассе аурелии в море 80 – 220 г м-2 её суточный рацион составлял 19 – 27 мг зоопл. м-2, что соответствует 0.8 – 2.7 % от энергетического эквивалента тела. Такая скорость выедания зоопланктона была недостаточной для компенсации обмена этого вида в данных условиях (4 – 6 % сут-1 относительно энергетического эквивалента тела). Обнаружен-ный дисбаланс в питании аурелии указывает на важность визуально недоучитываемых альтернативных источников пищи, и отчасти мог быть также обусловлен...

Introdução: O mastocitoma, uma das neoplasias malignas de pele mais comuns dos cães, é normalmente classificado em três graus histológicos [1]. Recentemente, um novo método de classificação foi proposto, subdividindo estes tumores em apenas duas classes [2], com intuito de minimizar variações entre observadores, principalmente em relação aos tumores de grau II, e de tornar mais precisa a avaliação prognóstica para esta neoplasia. Semelhantemente, diversos outros métodos histomorfológicos e imuno-histoquímicos têm sido propostos no intuito de prever o comportamento desta neoplasia e melhorar os tratamentos disponíveis [3]. Sabe-se que para o desenvolvimento tumoral há necessidade de interação entre células e outros elementos teciduais, além de atividade...

As enfermidades parasitárias dos animais de companhia têm apresentado crescente interesse científico, particularmente pelo estreito contato que esses animais vêm estabelecendo com os seres humanos e pela possibilidade de se comportarem como reservatórios de agentes etiológicos de algumas zoonoses graves para a saúde pública. Apesar das medidas terapêuticas e profiláticas atualmente disponíveis, enteroparasitas como Giardia spp., Criptosporidium spp., Isospora spp. e helmintos ainda são comumente encontrados em cães e gatos. Essas parasitoses apresentam sinais clínicos diversos, porém a diarreia é comumente observada. Este trabalho efetuou uma investigação coproparasitológica em filhotes caninos domiciliados com e sem diarreia no período de setembro de 2016...

Provedor de dados: 32
Autores: Roblero Méndez, Emmanuel.
En muchas regiones de México se enfrenta un desajuste entre la demanda del agua y su disponibilidad, principalmente debido a la distribución desigual  y a la calidad del agua. Debido las condiciones áridas y semiáridas del país, el riego es indispensable para la realización de la actividad agrícola, ya que el agua de lluvia no es suficiente para el crecimiento y desarrollo de los cultivos. Se ha estimado que en el 63% del territorio mexicano, el riego es indispensable, y que sólo en el 1.5% no es. En los usos de los recursos hídricos, el agrícola consume el 77% y es éste el que tiene las menores eficiencias. Por ello es recomendable implementar nuevas tecnologías para coadyuvar en la Conservación de la calidad y cantidad de este valioso recurso. Es así,...

Provedor de dados: 32
Autores: Roblero Méndez, Emmanuel.
En muchas regiones de México se enfrenta un desajuste entre la demanda del agua y su disponibilidad, principalmente debido a la distribución desigual  y a la calidad del agua. Debido las condiciones áridas y semiáridas del país, el riego es indispensable para la realización de la actividad agrícola, ya que el agua de lluvia no es suficiente para el crecimiento y desarrollo de los cultivos. Se ha estimado que en el 63% del territorio mexicano, el riego es indispensable, y que sólo en el 1.5% no es. En los usos de los recursos hídricos, el agrícola consume el 77% y es éste el que tiene las menores eficiencias. Por ello es recomendable implementar nuevas tecnologías para coadyuvar en la Conservación de la calidad y cantidad de este valioso recurso. Es así,...

Variable Ni isotope fractionation between Fe-oxyhydroxides and implications for the use of Ni isotopes as geochemical tracers
Provedor de dados: 5
Autores: Gueguen, Bleuenn; Sorensen, Jeffry V.; Lalonde, Stefan; Pena, Jasquelin; Toner, Brandy M.; Rouxel, Olivier.
Nickel (Ni) isotopes have recently emerged as a new biogeochemical tracer in marine environments, but our understanding of the mechanisms of Ni isotope fractionation in natural systems with regards to its fractionation by mineral surfaces is incomplete. This study aims to provide experimental constraints on Ni isotope fractionation during adsorption to goethite and 2-line ferrihydrite, two Fe minerals that vary in terms of distinct crystalline properties. We conducted two types of adsorption experiments: one with variable pH (5.0 to 8.0) and constant initial Ni concentration, one at a constant pH of 7.7 and variable initial Ni concentrations. Isotopic measurements were made on both the solid phase and the supernatant solutions in order to determine the Ni...

Coprostanol levels and organic enrichment in sediments of the Bilbao estuary (north of Spain)
Provedor de dados: 5
Autores: Saiz-salinas, Ji; Gonzalez-oreja, Ja.
An assessment was made of the distribution of the faecal sterol coprostanol (COP) in sediments in the Bilbao estuary. Concentrations of COP ranged from 135.15 to 10.77 mu g g(-1) dry weight, from the inner to the open estuary, with a mean value of 51.43 mu g g(-1); the highest concentrations were found near the mouths of several tributaries flowing into the estuary. Comparisons with ether published values indicate that sediments from the Bilbao estuary are affected by sewage pollution in a similar degree to that reported for other estuaries in the world. Organic enrichment and anaerobic sediment conditions prevail in three-fourths of its watercourse bed. Since the spatial distribution of several organic sedimentary parameters could be clearly correlated...

Provedor de dados: 5
Autores: Omnes, Marie-helene; Normant, Yvon; Suquet, Marc; Fauvel, Christian.
Egg production data from individual hand stripped female turbot were collected and analysed over several consecutive spawning seasons, on natural or shifted conditions. Egg quantity, egg viability and number of spawns were examined from one spawning season to the other, and inside the spawning season. These parameters seemed to increase from a year to the next one, except for the oldest fishes. Spawns were spread over a three-month period and occurred at the same time in the period in successive seasons for most females. Egg production seemed related to the feeding level and the earliness of spawning season appeared depended on the growth rate. Without sand substrate in tanks, injuries could increase therefore no significant differences were observed in...

Estimations of algal growth potential (AGP) of oyster-pond waters have been made by the use of bioassays and nutrient analysis. Data obtained demonstrated that nitrogen is the nutrient Iimiting AGP and that an important part of algal biomass is supported by organic nutrients. Such an uptake ranges from 0.6 to 30.7 µg-at.I-1 nitrogen ; which represents up to six times the total amount of inorganic nitrogen taken up. U.V oxydation and subsequent chemical analysis shown DON concentrations in oyster-pond waters varied with oyster presence or absence: values recorded were 10-40 µg-at N.I-1 when oysters were not present, and up to 50-60 µg-at N.I-1 when oysters were covering the bottom of the pond.

Résumé : Les 6 campagnes de chalutage réalisées en 1987 et 1988 ont permis d’évaluer les indices d’abondance des diverses ressources démersales, essentiellement poisson et céphalopodes, par strate, zone et, pour l’ensemble du plateau continental. Des estimations de biomasse apparente (77'000 tonnes en 1988) et de potentiel maximum exploitable (59'200 t. en 1988) ont aussi été avancées. La comparaison de ces résultats avec ceux des années 1982-1984 a fait ressortir une nette tendance à l’amélioration générale depuis 1987. Si la situation de la zone nord (Cap Blanc) demeure encore préoccupante par rapport à celle du sud, l’abondance globale des ressources du plateau a retrouvé un niveau peu inférieur à celui des années 1982-1983.

Simulating the Potential Distribution and Abundance of the Brown Marmorated Stink Bug (Halyomorpha halys) under Future Climate Scenarios in Switzerland
Provedor de dados: 21
Autores: Stöckli, Sibylle; Felber, Raphael; Haye, Tim.
The climate in Switzerland is changing. Depending on the emission scenario and time period, the projected increase in temperature is 2.7-4.8°C and the projected decrease in precipitation is 18-28%. There is scientific evidence that climate change will increase economic damage by agricultural pests. The prevention and management options of alien species are cost and time intensive.  Climate change will improve the long-term suitability of potential new areas and amplify the need for action. Therefore it is highly important to assess the risk of alien species under future climate conditions and to plan an efficient monitoring and to develop management strategies.  The brown marmorated stink bug (Halyomorpha halys) is an extremely polyphagous insect and has...

Estudio de parámetros hídricos foliares en trigo (Triticum aestivum L.) y su uso en selección de genotipos resistentes a sequía
Provedor de dados: 97
Autores: ORTIZ,MAURICIO; SILVA,HERMAN; SILVA,PAOLA; ACEVEDO,EDMUNDO.
Los parámetros hídricos foliares ys (potencial de solutos), CRA (contenido relativo de agua) y AO (ajuste osmótico) permiten caracterizar la respuesta de las plantas frente al estrés hídrico e identificar aquellos genotipos mejor adaptados. Sin embargo, estos parámetros presentan una gran influencia del medioambiente lo que dificulta su análisis. En este trabajo se planteó la hipótesis de que es posible caracterizar y seleccionar genotipos resistentes a sequía en base a la evolución de los parámetros hídricos foliares en campo. Se cultivaron 31 genotipos de trigo (Triticum aestivum L.) en dos ensayos de campo, uno regado y otro no regado que recibió sólo 218,3 mm de lluvia invernal. El diseño fue de bloques al azar con dos repeticiones. Entre los 77 y 121...

Efficiency of data transformation strategies is evaluated to correct heterogeneity among cattle in the genetic evaluation of bulls, cows and progenies. Four data structures of bovine weaning weights were simulated: herds with and without heterogeneity for means and variances, and herds with and without genetic connectedness. In the genetic evaluations, data were used in the original scale and transformed (Logarithmic, Square root, standardization and ratio by phenotypic standard deviation). The evaluated data transformation strategies were not efficient in eliminating the negative effects of heterogeneity among cattle in the genetic evaluation of bulls, cows and progenies.

Agriculture has straight and indirect contribution to boost the economy of Pakistan. Wheat and paddy are among the major rotational crops of Pakistan. The straw management in combine harvested in wheat fields is a major problem. In the past the residual wheat straw in convectional harvesting was burnt in the field which resulted losses of 80% of Nitrogen, 25% P, 21% K and 4-60% S. To overcome this problem, locally available wheat straw chopper is used for cutting and collecting the wheat straw left behind the combine harvesters. These locally developed wheat straw choppers are heavy in weight having lower machine efficiency. A wheat straw chopper has been modified using locally available materials making it light weight and more efficient. The performance...

Studies have shown that the frequency or worsening of sleep disorders tends to increase with age and that the ability to perform circadian adjustments tends to decrease in individuals who work the night shift. This condition can cause consequences such as excessive sleepiness, which are often a factor in accidents that occur at work. The present study investigated the effects of age on the daytime and nighttime sleep patterns using polysomnography (PSG) of long-haul bus drivers working fixed night or day shifts. A total of 124 drivers, free of sleep disorders and grouped according to age (&lt;45 years, N = 85, and ≥45 years, N = 39) and PSG timing (daytime (D) PSG, N = 60; nighttime (N) PSG, N = 64) participated in the study.

Autores: Domínguez Lagunes, Maira Antonia.
La investigación se realizó en dos etapas. El objetivo de la primera etapa fue documentar el conocimiento local sobre Brosimum alicastrum como árbol forrajero. Las entrevistas con los ganaderos mostraron que el 83% conocía aspectos ecológicos del árbol, el 9% la biología y un 77% aspectos sobre manejo del árbol; esta especie cayó en el desuso a partir del reparto agrario (1940) cuando la delimitación de las parcelas restringió el acceso a los árboles. Se concluyó que existe conocimiento sobre la utilización del árbol aunque limitado, y que el desarrollo tecnológico propició a que este recurso fuera cayendo en desuso; aunque aún existe interés en recuperarlo y utilizarlo. El objetivo de la segunda etapa considerando la primera, fue analizar el crecimiento...

In January 2001, approximately 23 x 106 ha of land in the U.S. National Forest System were slated to remain roadless and protected from timber extraction under the Final Roadless Conservation Rule. We examined the potential contributions of these areas to the conservation of biodiversity. Using GIS, we analyzed  the concordance of inventoried roadless areas (IRAs) with ecoregion-scale biological  importance and endangered and imperiled species distributions on a scale of 1:24,000.  We found that more than 25% of IRAs are located in globally or regionally outstanding ecoregions and that 77% of inventoried roadless areas have the potential to conserve threatened, endangered, or imperiled species. IRAs would increase the conservation reserve network...

Autores: Leenhouts, Bill; U. S. Fish and Wildlife Service; Bill_Leenhouts@.fws.gov.
Wildland fire has been an integral part of the landscape of the conterminous United States for millennia. Analysis of contemporary and pre-industrial (~ 200 - 500 yr BP) conditions, using potential natural vegetation, satellite imagery, and ecological fire regime information, shows that wildland fires burned 35 - 86 x 106 ha (megahectares) annually in the pre-industrial era, consuming 530 - 1230 teragram (Tg) of biomass. At present, in comparison, 5 - 7 Mha/yr burn, consuming 77 - 189 Tg of biomass annually. If historic fire regimes were restored to non-urban and non-agricultural lands today, 18 - 43 Mha would burn annually, consuming 285 - 602 Tg of biomass. For each era, 11 biomass (wildland and agricultural) burning emissions were estimated, and...

High density process to cultivate Lactobacillus plantarum biomass using wheat stillage and sugar beet molasses
Provedor de dados: 69
Autores: Krzywonos,Magorzata; Eberhard,Thomas.
Background: Owing to the growing interest in biofuels, the concept of a biorefinery where biomass is converted to a variety of useful products is gaining ground. We here present how distillery waste is combined with a by-product from a sugar production, molasses, to form a medium for the growth of Lactobacillus plantarum with yields and biomass densities comparable with conventional industrial media. Such approach enables a cost-effective utilization of the problematic wastewater from ethanol and a by-product from sugar production. It is the first approach that attempts to find low-cost media for the production of Lactobacillus plantarum biomass. Results: This study suggests that sieved wheat stillage enriched by adding 1.77 g/l yeast extract and 10%...

Autores: Postiglioni,Alicia; García,Cristina B; Rincón,Gonzalo; Arruga,M. Victoria.
Robertsonian translocation (rob(1;29)) is the most frequent structural chromosomal abnormality in cattle. Heterozygous carriers have a normal phenotype but show a 3-5% decrease in fertility. Chromatin decondensation was evaluated similar to the inactive X chromosome when submitted to demethylating agent. Based on this result, and the concept that imprinted genes are essential in embryonic development, we decided to query genes located on BTA1 and BTA29 that could undergo genome imprinting. The collagen typeVIII-Î±1 (Col8A1) acted on extracellular matrix structural proteins. DNA bisulfite conversion and sequentiation methods were used to compare its differential methylation patterns. It was performed on eight Creole cattle DNA blood samples from normal and...

Isomaltulose is a structural isomer of sucrose commercially used in food industries. Glucosyltransferase produced by Erwinia sp. D12 catalyses an intramolecular transglucosylation of sucrose giving isomaltulose. The Experimental design and response surface methodology were applied for the optimization of the nutrient concentration in the culture medium for the enzyme production in shaken flasks at 200 rpm and 30ºC. The three variables involved in this study were sugar cane molasses, bacteriological peptone and yeast extract Prodex Lac SD®. The statistical analysis of the results showed that, in the range studied, all the factors had a significant effect (p &lt; 0.05) on glucosyltransferase production and the highest enzyme activity was observed in culture...

CROP COEFFICIENT REGIONALIZATION FOR IRRIGATED AGRICULTURE PLANNING IN MARANHÃO STATE -BRAZIL
Provedor de dados: 70
Autores: Silva,Wilson A. Da; Santana,Jhonata S.; Silva,Cristiane M. Da; Nunes,Acassio A.
ABSTRACT: Irrigated agriculture has emerged as a necessary technology to achieve greater productivity, mainly by supplying the water requirements of agricultural crops in critical periods, especially for those regions where natural rainfall is insufficient to meet these requirements. The daily water consumption of crops is strongly influenced by local weather conditions, which justifies the need for regionalized studies of the parameters influencing the water depth to be applied. The crop coefficient (Kc) is perhaps the most important parameter because it interferes directly with the crop water requirements. This index must be determined for each region, thus avoiding the use of reference values meant for other climatic conditions, causing loss of...

Provedor de dados: 70
Autores: Amaral,André C. do; Kunz,Airton; Steinmetz,Ricardo L. R.; Cantelli,Fábio; Scussiato,Lucas A.; Justi,Karin C.
The industrial swine production is characterized by generation of significant effluent amounts that require treatment. The most adopted practices by Brazilian swine farmers have been wastewater storage in lagoons and its subsequent use as a biofertilizer. Nutrient accumulation in soil and water creates the need for an effective management of these residues. The anaerobic digestion process is an important alternative and low-cost treatment for organic matter reduction. However, its efficiency is limited by the digester capacity of solid degradation, especially at low hydraulic retention times. Thus, the present study aimed to verify the behavior of an upflow anaerobic digester by increasing the organic loading rate. This was accomplished in three stages...

Autores: ESCOBAR HUERTA,GUSTAVO; SANTIBÁÑEZ TORO,JESSICA; ORTIZ,JUAN CARLOS.
This study describes a new species of lizard of the genus Liolaemus (L. lonquimayensis), without precloacal pores, associated with the lava flows of the Lonquimay volcano in the Región de la Araucanía, Chile. This species belongs to the elongatus clade, and is a sister lineage of L. elongatus. L. lonquimayensis differs from its sister species, L. elongatus, in the total absence of precloacal pores, smaller maximum SVL (69.7 mm in L. lonquimayensis and 91.0 mm in L. elongatus), greater number of midline scales (88 in L. lonquimayensis and 77 in L. elongatus), body color light grey to black in L. lonquimayensis and light to dark brown in L. elongates. L. lonquimayensis has an black occipital band formed by small black lines arranged horizontally flanked by...

Nonlinear correlation by using invariant identity vectors signatures to identify plankton
Provedor de dados: 72
Autores: Fimbres-Castro,Claudia; Álvarez-Borrego,Josué; Vázquez-Martínez,Irene; Espinoza-Carreón,T. Leticia; Ulloa-Pérez,A. Elsi; Bueno-Ibarra,Mario A.
In this paper a new methodology to recognize radk&gt;larians is presented. This system is invariant to position, rotation and scale by using identity vectors signatures (Is) obtained for both the target and the problem image. In this application, / is obtained by means of a simplification of the main features of the original image in addition of the properties of the Fourier transform. Identity vectors signatures are compared using nonlinear correlation. This new methodology recognizes objects in a more simple way. It has a low computational cost of approximately 0.02 s per image. In addition, the statistics of Euclidean distances is used as an alternative methodology for comparison of the identity vectors signatures. Also, experiments were carried out in...

Effect of PHA and LPS on the Activity of Nonspecific Cytotoxic Cells and Macrophages of Rainbow Trout (Oncorhynchus mykiss)
Provedor de dados: 72
Autores: Gómez,Leonardo A; Cortés,Raúl; Smith,Carlos T.
This work studied the effect of the lectin phytohaemagglutinin (PHA) and bacterial lipopolysaccharide (LPS) on the activity of nonspecific cytotoxic cells (NCCs) and macrophages of peripheral blood in the rainbow trout. NCCs are cells of the innate immunity, homologues to Natural Killer (NK) cells of mammals, capable of eliminating cells infected with intracellular pathogens and also tumoral cells. Their lytic activity is mediated by the perforin/granzyme system and the Fas receptor-Fas ligand (FasR-FasL) system. Activity of NCCs was evaluated by their capacity to lyse HL-60 tumor cells. On the other hand, macrophages eliminate microorganisms by several mechanisms, including the production of reactive oxygen species (ROS) and nitric oxide (NO). Results...

Allochthonous and autochthonous components from gizzard grit of Theristicus melanopis in anthropogenic pastures of southern chile
Provedor de dados: 72
Autores: Gantz,Alberto; Valdivia,Carlos E; Yañez,Miguel; Sade,Soraya.
Numerous vertebrates, and in particular birds, ingest stones (geo-gastrolites) to favour the breakdown and digestion of food in the muscular stomachs. Between 1993 and 1994 we evaluated the quantity, relative abundance and quality of autochthonous (geo-gastrolites) and allochthonous (pieces of glass) components of the grit in gizzards of black-faced ibis (Theristicus melanopis) inhabiting the pastures of southern Chile. Grit elements were present in 32 out of 48 (66,7%) of all gizzard analysed. A total of 572 particles were recorded from which, 69.1% corresponded to autochthonous elements and 27.8% were allochthonous particles. Both components are similar in shape; however glass contributes considerably more in terms of mass. Gender differences reveal that...

Autores: Arrieta,Marina Patricia; Ferrándiz,Santiago; Rayón,Emilio; López,Juan.
Los ácaros ectoparásitos son parásitos que aumentan su tamaño en varios órdenes de magnitud cuando se alimentan y alcanzan su estado adulto. Esclarecer los mecanismos por los cuales una cutícula rígida puede adaptarse a un aumento de volumen importante, cobra importancia para el diseño de fórmulas que bloquen dicho crecimiento y por lo tanto el desarrollo de estos parásitos, y como modelo para el desarrollo de nuevos biomateriales. En este trabajo se realizó una investigación morfológica y química de la cutícula de ácaros Ornithodoros erraticus hembra en estado adulto en ayunas y alimentadas. Mediante imágenes de microscopía electrónica de barrido se muestra que la morfología en forma de pliegues permite un estiramiento de la cutícula en todos los ejes del...

Autores: Soto,Gerardo E; Vergara,Pablo M; Hahn,Ingo J; Pérez-Hernández,Christian G; Lizama,Marlene E; Baumeister,Julia; Pizarro,Jaime.
The level of specialization of endemic island birds to their native habitats could contribute importantly to increase their extinction risk. We used abundance obtained from mist-netting and radio telemetry data from one individual to determine the micro-habitat use pattern of Juan Fernandez Tit-tyrants (Anairetes fernandezianus) within native forest. The tracked male tit-tyrant established its home range exclusively in core native forest areas. Regression models of abundance and Resource Utilization Functions showed strong micro-habitat preferences of tit-tyrants. The abundance and utilization probabilities of tit-tyrants declined with distance to exotic shrub and increased with distance to human created gaps. Natural heterogeneity in micro-habitat...

Diversas bacterias asociadas a macroalgas pueden usar ficocoloides como fuente de carbono. Las bacterias de la Antártica, poseen características fisiológicas adaptativas que habrían evolucionado para permitir su supervivencia y funcionamiento dentro de las condiciones adversas de ese ecosistema. Por lo tanto, bacterias aisladas desde algas antárticas podrían tener la capacidad de degradar enzimáticamente azúcares complejos a temperaturas inferiores que aquellas aisladas desde zonas más cálidas, lo que potencialmente podría tener aplicaciones en la mejora en procesos industriales que utilizan enzimas. El análisis del gen ribosomal 16S indica que la cepa bacteriana aislada desde algas varadas en la Isla Rey Jorge (Antártica), pertenece al género Bacillus. El...

Confirmation of the presence of Alsodes pehuenche Cei, 1976 (Anura, Alsodidae) in Chile: morphological, chromosomal and molecular evidence
Provedor de dados: 72
Autores: Correa,Claudio; Pastenes,Luis; Iturra,Patricia; Calderón,Pilar; Vásquez,Dayana; Lam,Natalia; Salinas,Hugo; Méndez,Marco A.
The presence of Alsodespehuenche in Chile was reported in the year 2010, based on the observation of larvae near the Chilean-Argentinean border, about 3 km east of the northeast corner of the Laguna del Maule (Región del Maule, Chile). The taxonomic history of this species dates from 1965, with the re-discovery of Telmatobius montanus (which was later transferred to the genus Alsodes) in two localities, near the Laguna del Maule and Valle Pehuenche, located in Chile and Argentina, respectively. The literature review shows that the locality of Argentina described in 1965 became the type locality of A. pehuenche, while the Chilean locality was ignored; thus this latter locality continues to be a valid record for A. montanus. In this study we provide...

Autores: Gallardo,Víctor Ariel; Espinoza,Carola; Fonseca,Alexis; Musleh,Selim.
Durante el primer estudio nacional de la zona de mínimo oxígeno (ZMO) y del macrobentos animal costa afuera del norte de Chile (1962), se descubrió una comunidad bentónica compuesta de bacterias filamentosas multicelulares gigantes en los sedimentos fuertemente reducidos entre 50 y182 m. La masiva abundancia de filamentos bacterianos visibles a simple vista y el extremadamente escaso macrobentos animal, fueron rasgos inesperados. Más recientemente (2004) un nuevo ensamble de bacterias filamentosas multicelulares más pequeñas fue descubierto distribuido en los sedimentos más reducidos sub-superficiales del tapiz bacteriano. Hoy reconocemos que este ecosistema dominado por procariotas constituye un rasgo mayor y distinto al nivel mundial el que aquí...

Glutathione S-transferase M1 (GSTM1) polymorphism in two Brazilian populations
Provedor de dados: 74
Autores: Hatagima,Ana; Klautau-Guimarães,Maria Nazaré; Silva,Felizardo Penalva da; Cabello,Pedro Hernan.
The distribution of GSTM1 phenotype frequencies was studied in two Brazilian samples composed of healthy and unrelated blood donors of both sexes ranging in age from 18 to 61 years. The first sample consisted of 658 individuals from Rio de Janeiro, and the second included 179 individuals from Brasília. The GSTM1 phenotypes were detected using PCR reactions and subsequent digestion by the restriction enzyme HaeII. The GSTM1 null phenotype frequency was 46% and 49% for Rio de Janeiro and Brasília samples, respectively. The GSTM1 phenotype distributions were not in agreement with Hardy-Weinberg equilibrium in either sample, chi²1 = 11.49 (P &lt; 0.001) for Rio de Janeiro and chi²1 = 6.77 (P &lt; 0.01) for Brasília.

Autores: Dejean,Cristina B.; Crouau-Roy,Brigitte; Goicoechea,Alicia S.; Avena,Sergio A.; Carnese,Francisco R.
The allelic variability of four dinucleotide microsatellites located in the HLA region (MOGc, D6S265, MIB, and TNFa) was analyzed in 67 individuals representing three Amerindian populations of the Argentine Gran Chaco: Toba, Wichi and Chorote. Genomic DNA was prepared from peripheral blood and DNA was extracted using the standard phenol-chloroform procedure. Alleles were identified by PCR, using an end-labelled reverse oligonucleotide primer (fluorescent 6 - Fam labeling). Despite the low number of samples studied, a high level of gene diversity was observed in each population and for each locus. Moreover, the mean number of alleles was 7.7, 5.3, 10.0, and 7.0 at loci MOGc, D6S265, MIB and TNFa, respectively. Differentiation tests between pairs of...

Autores: Mantellatto,Aline Meira Bonfim; González,Susana; Duarte,José Maurício Barbanti.
Abstract Natural history museum collections constitute an invaluable patrimony of biological diversity for analysing the taxa distribution and evolution. However, it is very common to discover taxonomic misidentification in museum collections based on incorrect data. The aim of this research was to identify brocket deer species (Mazama genus) using molecular markers. We collected 199 samples, performed DNA extraction and species identification using a specific mitochondrial marker based on a fragment of cytochrome b (Cytb) for Neotropical deer. We achieved the amplification and sequencing of 77 specimens and verified that 26% of the skulls were wrongly identified. Moreover, in the museum collections 57% of the specimens were only identified as Mazama sp,...

Autores: Machado-Ferreira,Erik; Piesman,Joseph; Zeidner,Nordin S; Soares,Carlos A.G.
As Rocky Mountain Spotted Fever is the most common tick-borne disease in South America, the presence of Rickettsia sp. in Amblyomma ticks is a possible indication of its endemicity in certain geographic regions. In the present work, bacterial DNA sequences related to Rickettsia amblyommii genes in A. dubitatum ticks, collected in the Brazilian state of Mato Grosso, were discovered. Simultaneously, Paracoccus sp. was detected in aproximately 77% of A. cajennense specimens collected in Rio de Janeiro, Brazil. This is the first report of Paracoccus sp. infection in a specific tick population, and raises the possibility of these bacteria being maintained and/or transmitted by ticks. Whether Paracoccus sp. represents another group of pathogenic Rhodobacteraceae...

Low doses of gamma ionizing radiation increase hprt mutant frequencies of TK6 cells without triggering the mutator phenotype pathway
Provedor de dados: 74
Autores: Ayres,Flávio Monteiro; Cruz,Aparecido Divino da; Steele,Patricia; Glickman,Barry W.
The TK6 lymphoblastoid cell line is known to be mismatch repair (MMR) and p53 proficient. Deficiency in MMR results in a mutator phenotype characterized by microsatellite instability (MSI) and increased hprt mutant frequency (MF). Increased hprt MF is also a biomarker of effect for exposure to ionizing radiation. In order to test if a mutator phenotype could be induced by low doses of gamma ionizing radiation, an hprt cloning assay and a MSI investigation were performed after radiation exposure. The spontaneous MF was 1.6 x 10-6. The groups exposed to 0.2, 0.5 and 1.0 Gy had hprt MFs of 2.3, 3.3 and 2.2 x 10-6, respectively. The spontaneous MSI frequency per allele in non-selected cells was 5.4 x 10-3, as evidenced at the loci D11S35, nm23-H1, D8S135 and...

Provedor de dados: 74
Autores: Ventura,Henrique T.; Lopes,Paulo S.; Peloso,José V.; Guimarães,Simone E.F.; Carneiro,Antonio Policarpo S.; Carneiro,Paulo L.S.
The association between carcass and ham traits in a pig population used to produce dry-cured ham was studied using canonical correlation analysis. The carcass traits examined were hot carcass weight (HCW), backfat thickness (BT) and loin depth (LD), and the ham traits studied were gross ham weight (GHW), trimmed ham weight (THW), ham inner layer fat thickness (HIFT), ham outer layer fat thickness (HOFT), pH (pH) and the Göfo value. Carcass and ham traits are not independent. The canonical correlations (r) between the carcass and ham traits at 130 kg were 0.77, 0.24 and 0.20 for the first, second and third canonical pair, respectively, and were all significant (p &lt; 0.01) by the Wilks test. The corresponding canonical correlations between the three...

Autores: Faleiro,Fábio Gelape; Vinhadelli,Wender Santos; Ragagnin,Vilmar Antonio; Corrêa,Ronan Xavier; Moreira,Maurilio Alves; Barros,Everaldo Gonçalves de.
Rust, caused by the fungus Uromyces appendiculatus, may cause a significant loss to common bean (Phaseolus vulgaris L.) yield. RAPD markers tightly linked to the resistance genes may be used in breeding programs to aid the development of rust-resistant bean cultivars. In this sense, the objective of the present work was to identify RAPD markers linked to a rust resistance gene block present in the cultivar Ouro Negro. Two hundred and fourteen F2 individuals from a cross between the resistant cultivar Ouro Negro and the susceptible cultivar US Pinto 111 were inoculated with a mixture of eight races of U. appendiculatus. The segregation ratio obtained suggested that resistance is monogenic and dominant. Bulked segregant analysis was used in conjunction with...

Phylogenetic analysis of 16S mitochondrial DNA data in sloths and anteaters
Provedor de dados: 74
Autores: Barros,Maria Claudene; Sampaio,Iracilda; Schneider,Horacio.
We sequenced part of the 16S rRNA mitochondrial gene in 17 extant taxa of Pilosa (sloths and anteaters) and used these sequences along with GenBank sequences of both extant and extinct sloths to perform phylogenetic analysis based on parsimony, maximum-likelihood and Bayesian methods. By increasing the taxa density for anteaters and sloths we were able to clarify some points of the Pilosa phylogenetic tree. Our mitochondrial 16S results show Bradypodidae as a monophyletic and robustly supported clade in all the analysis. However, the Pleistocene fossil Mylodon darwinii does not group significantly to either Bradypodidae or Megalonychidae which indicates that trichotomy best represents the relationship between the families Mylodontidae, Bradypodidae and...

Efficiency of IRAP and ITS-RFLP marker systems in accessing genetic variation of Pyrenophora graminea
Provedor de dados: 74
Autores: Zein,Imad; Jawhar,Mohammed; Arabi,Mohammed Imad Eddin.
The usefulness of IRAP (inter-retrotransposon amplified polymorphism) and ITS-RFLP (restriction of PCR-amplified internal transcribed spacers of the rDNA) markers in the analysis of 39 Pyrenophora graminea isolates was determined. Each marker system could discriminate between all of the isolates in detecting polymorphism, albeit with variable efficiency. IRAP and ITS-RFLP produced 85% and 77% polymorphic bands, respectively, with a corresponding mean polymorphic information content (PIC) of 0.38 and 0.36. The IRAP marker index ratio (2.41) was higher than ITS-RFLP (1.50). On one hand, the quality nature of data (QND) was higher for ITS-RFLP (0.169) than IRAP (0.093).

Autores: Ferreira,Francileide Lisboa; Leal-Mesquita,Emygdia Rosa; Santos,Sidney Emanuel Batista dos; Ribeiro-dos-Santos,Ândrea Kely Campos.
Five loci (vWA1, F13A1, D12S67, Apo-B and D1S80) were investigated by polyacrylamide gel electrophoresis followed by silver staining in a sample of 177 individuals from the population of São Luís, State of Maranhão, Brazil. A total of 70 different alleles were identified. A statistically significant deviation from the Hardy-Weinberg equilibrium was observed in a single locus (F13A1, p = 0.0075). The average heterozygosity (H) was estimated at 77.7%, the mean number of alleles per locus as 14. The PD (capacity of genotype differentiation at each locus) ranged from 88.9% (vWA1) to 96.7% (F13A1). The combined PE (power of exclusion) of these five loci was 99.8%. In terms of racial admixture (42% European, 39% Indian, and 19% African Black ancestry), São Luís...

Complete sequence and comparative analysis of the chloroplast genome of Plinia trunciflora
Provedor de dados: 74
Autores: Eguiluz,Maria; Yuyama,Priscila Mary; Guzman,Frank; Rodrigues,Nureyev Ferreira; Margis,Rogerio.
Abstract Plinia trunciflora is a Brazilian native fruit tree from the Myrtaceae family, also known as jaboticaba. This species has great potential by its fruit production. Due to the high content of essential oils in their leaves and of anthocyanins in the fruits, there is also an increasing interest by the pharmaceutical industry. Nevertheless, there are few studies focusing on its molecular biology and genetic characterization. We herein report the complete chloroplast (cp) genome of P. trunciflora using high-throughput sequencing and compare it to other previously sequenced Myrtaceae genomes. The cp genome of P. trunciflora is 159,512 bp in size, comprising inverted repeats of 26,414 bp and single-copy regions of 88,097 bp (LSC) and 18,587 bp (SSC). The...

Reciprocal recurrent selection effects on the genetic structure of tropical maize populations assessed at microsatellite loci
Provedor de dados: 74
Autores: Pinto,Luciana Rossini; Vieira,Maria Lucia Carneiro; Souza Jr.,Claudio Lopes de; Souza,Anete Pereira de.
A modified reciprocal recurrent selection (RRS) method, which employed one cycle of high-intensity selection, was applied to two tropical maize (Zea mays L.) populations, BR-105 and BR-106, originating the improved synthetics IG-3 and IG-4, respectively. In the present study the effects of this kind of selection on the genetic structure of these populations and their synthetics were investigated at 30 microsatellite (SSR) loci. A total of 125 alleles were revealed. A reduction in the number of alleles was observed after selection, as well as changes in allele frequencies. In nearly 13% (BR-105) and 7% (BR-106) of the loci evaluated, the changes in allele frequencies were not explained, exclusively due to the effects of genetic drift. The effective...

We investigated the occurrence of Factor XI (FXI) deficiency syndrome in the following Indian dairy animals: Bos taurus Holstein-Friesian and Jersey cattle, Bos indicus Indian cattle breeds, B. taurus x B. indicus crossbreds and the river buffalo Bubalus bubalis. Factor XI deficiency is an autosomal recessive bleeding disorder known to affect Holstein cattle worldwide. A total of 1001 dairy animals, mainly bulls, were genotyped to detect the mutation within exon 12 of the gene encoding for factor XI. Two Holstein bulls were detected as heterozygous (carrier) for FXI deficiency, giving a carrier frequency of 0.6% in Indian Holstein cattle. None of the other cattle or buffalo breeds was found to be a carrier for FXI. Sequence comparison between normal and...

Abstract The giant anteater (Myrmecophaga tridactyla, Pilosa, Linnaeus 1758) belongs to the mammalian order Pilosa and presents a large distribution along South America, occupying a great variety of habitats. It is listed in the IUCN Red List of threatened species as Vulnerable. Despite threatened, there is a lack of studies regarding its genetic variability. The aim of this study was to examine the genetic diversity and patterns of genetic structure within remaining populations. We analyzed 77 individuals from seven different populations distributed in four biomes across Brazil: Cerrado, Pantanal, Atlantic Forest and Amazon Forest. We sequenced two mitochondrial markers (control region and Cyt-b) and two nuclear markers (AMELY and RAG2). We found high...

Brazilian poultry industry has reached a high level of development in both meat and egg production as a result of constant technological modernization. Further improvements can be achieved through genomics, but before this can be accomplished, a better understanding of gene expression profiles and nucleotide polymorphisms is necessary. Since animal physiology is directly or indirectly controlled by the pituitary and hypothalamus, the aim of the present work was to identify and analyze genes expressed in these tissues in chicken lines with different growth potential. Two pituitary and hypothalamus cDNA libraries from 21 day broiler (TT) and layer (CC) chickens lines were constructed and allowed identification of 3,074 unique sequences and 77 single...

Autores: Pimentel,Eduardo da Cruz Gouveia; Queiroz,Sandra Aidar de; Carvalheiro,Roberto; Fries,Luiz Alberto.
The problem of multicollinearity in regression analysis was studied. Ridge regression (RR) techniques were used to estimate parameters affecting the performance of crossbred calves raised in tropical and subtropical regions by a model including additive, dominance, joint additive or "profit heterosis" and epistatic effects and their interactions with latitude in an attempt to model genotype by environment interactions. A software was developed in Fortran 77 to perform five variant types of RR: the originally proposed method; the method implemented by SAS; and three methods of weighting the RR parameter lambda. Three mathematical criteria were tested with the aim of choosing a value for the lambda coefficient: the sum and the harmonic mean of the absolute...

Inheritance of fruit color and pigment changes in a yellow tomato (Lycopersicon esculentum Mill.) mutant
Provedor de dados: 74
Autores: Rêgo,Elizanilda R. do; Finger,Fernando L.; Casali,Vicente W.D.; Cardoso,Antônio A.
A naturally occurring yellow tomato fruit mutant cv. Santa Clara was reciprocally crossed with the red wild type, after which F1 plants were self pollinated or backcrossed with both parents. Plants from F1 generations produced all fruits with a homogeneous deep red color when ripe. F2 plants showed a 3:1 red:yellow segregation of fruit color, and 100% red when backcrossed with red wild type or 1:1 red:yellow segregation in backcrosses with the yellow mutant; hence, yellow fruit color was determined by a recessive allele. Based on reciprocal crosses, fruit color is unlikely to be determined by maternal genes. Accumulation of lycopene dropped by 99.3% and&lt;FONT FACE="Symbol"&gt; b&lt;/font&gt;-carotene by 77% in ripe yellow fruits, compared to the red wild...

ABSTRACT Tropical floriculture has increased significantly in the last decade due to a growing worldwide market trend of consuming exotic, colorful, beautiful and durable flowers. Among the tropical floriculture products, ornamental gingers, species belonging to the families Zingiberaceae and Costaceae, have high potential for ornamental use, both for landscaping, for cut and potted flower and foliage. However, little information can be found in literature when it comes to crop fertilization, mainly concerning nitrogen fertilization, quite important to tropical soils which are poor in organic matter resource. Thus, this study aimed to evaluate application of nitrogen doses, using fertigation for growing ornamental ginger under protected cultivation. The...

Provedor de dados: 75
Autores: Echer,Márcia de M; Zoz,Tiago; Rossol,Charles Douglas; Steiner,Fábio; Castagnara,Deise D; Lana,Maria do C.
An experiment was conducted to evaluate the effect of plant spacing and nitrogen fertilization on Swiss chard's yield, from September to November 2009. The experimental design was of randomized blocks in split plot with four replications. In the plots were allocated the two plant spacings (0.30 and 0.50 m) and in the subplots the five doses of nitrogen (0, 40, 80, 120 and 160 kg ha-1). The crop was harvested 90 days after transplanting. The plant spacing of 0.50 m provided increased production of total fresh weight of shoot (961.7 g plant-1) and marketable (873.1 g plant-1). However, the highest total yield (77.8 t ha-1) and marketable (64.5 t ha-1) was achieved with the smaller spacing between plants (0.30 m). The N rates applied in coverage until 160 kg...

ABSTRACT Offering new products obtained from potatoes is a market opportunity which may increase and motivate the consumption of this tuber. It also can contribute for waste reduction and ensure market for growers. Thus, we aimed to produce potato flour and to evaluate the effect of blanching on the physiochemical characteristics of this product after 3-month storage at room temperature. Potatoes cultivar Agata were used to make unblanched and blanched flour, through thermal treatment at 97°C for 5 min. The unblanched potato flour presented significantly smaller contents of moisture (p= 0.006), proteins (p= 0.001) and soluble fibers (p= 0.024), as well as color alteration. However, it presented higher phenolic compound content (23.77%). The blanched potato...

In the S. droebachiensis ontogenesis the maximum-to-average rations values increase. This permits large animals to shorten the period of transition from the maximum ration to the average one and to keep the latter at a relatively constant level. The variations in the average daily rations are associated with the period of food digestion, therefore the digestion period may be measured without using the labelled food. Studies on the processes of accumulation and assimilation by Strongylocentrotus droebachiensis of the suspendable and soluble substrates of different chemical nature by the method of chamber analysis made it possible to find out significant peculiarities of these processes.

Энергетический баланс и соотношение продукции  и метаболизма у тихоокеанской устрицы  Crassostrea gigas (Thunberg), интродуцированной в Черное море
Provedor de dados: 13
Autores: Золотницкий, А. П.
Исследован энергетический баланс и динамика составляющих элементов у тихоокеанской устрицы, интродуцированной в Черное море. Выявлена тесная связь между К2 и удельной скоростью роста (Сb), которая описывается гиперболической функцией Михаэлиса-Ментен. Соленость воды, близкая к 18 ‰, является нижним пределом для нормального функционирования тихоокеанской устрицы, снижение ее на 3 - 4 ‰ нарушает нормальное течение процессов жизнедеятельности этого вида.

Исследован зоопланктон Севастопольской  бухты после постройки мола, ограничивающего ее водообмен с открытым морем. Состав и  количество зоопланктона в большей степени зависели от сезона, чем от уровня загрязнения. Зимой,  вследствие усиления ветровой деятельности и улучшения водообмена с открытой  частью моря, численность, биомасса и количество видов зоопланктона на отдельных станциях бухты различались меньше. После постройки мола у входа в Севастопольскую бухту солоноватоводная копепода  Calanipeda aquae dulcis распространилась по всей акватории бухты. Общее  число  видов, величины численности и биомассы зоопланктона,а также  процентное  содержание Acartia clausi  на  станциях различались летом, когда ветровая деятельность ослабевала, а антропогенное...

Close relation between internal (level of fat stores) and external (temperature fall) impulses of wintering migration of Azov and Black Sea anchovies Engraulis encrasicolus maeoticus and E. e. ponticus (“dosage principle”) was revealed. Schools with high fatness begin migration at more high temperature than that ones with low fatness. Intensity of migration also correlates with level of fatness. Regularities obtained may be used for study of wintering migration of other truly marine fishes.

Высокие показатели заселённости  гигантской устрицы Crassostrea gigas (Thunberg, 1793), культивируемой в Чёрном море, сверлящей губкой Pione vastifica (Нancock, 1848) свидетельствуют о её восприимчивости к заселению этой губкой. Более высокая обсемененность микроорганизмами внутренних органов и мантийной полости заселённых губками устриц, в сравнении с незаселёнными моллюсками, может свидетельствовать о положительной корреляции между встречаемостью у устриц губки и их  заселённостью микроорганизмами.

Проведен анализ многолетней изменчивости размерно-возрастной структуры поселений мидий в северо-западной части Черного моря. Выявленные межгодовые различия свидетельствуют о том, что в современных экологических условиях на северо-западном шельфе Черного моря продолжаются негативные процессы, которые увеличивают смертность моллюсков и приводят к неуклонному омоложению возрастной структуры их поселений. Это вызывает уменьшение продолжительности жизни черноморской мидии и снижение ее репродукционного потенциала.

Short-term spider community monitoring after cattle removal in grazed grassland
Provedor de dados: 76
Autores: Silva,Guilherme O. da; Ott,Ricardo.
ABSTRACT. At the Pampa Biome, grazing, like others disturbances, affects fauna and flora, creating heterogeneity in the environment. Little is known about how the diversity and richness of arthropods change during this impact. To improve the knowledge of how spider diversity is affected by grazing, experiments were realized at Pampa. The hypothesis is that abundance of spider will be different when comparing grazed and ungrazed areas. A paired block, with two areas of one hectare each, was established in three areas in the Environmental Protection Area of Ibirapuitã (APA Ibirapuitã), state of Rio Grande do Sul, Brazil. One of these hectares was closed with fences, excluding the catle grazing, in August of 2012. Samplings were realized in November of 2011,...

The South American sea lion, Otaria flavescens (Shaw, 1800) population is steadily expanding along the Patagonian coast of Argentina in the last decades. However, little is known about the feeding ecology of the species in the area. The aim of this study was to analyze the food habits of O. flavescens from 91 scats collected at Río Negro province, during the winter and spring of 2005. Fish occurred in 96% of scats containing prey remains, followed by cephalopods (26%). Raneya brasiliensis (Kaup, 1856) was the most frequent and abundant species occurring in 58.6% of samples and constituting almost 50% of fish predated. Second in importance were Porichthys porosissimus (Cuvier, 1829) and Cynoscion guatucupa (Cuvier, 1830) in terms of occurrence (%FO 20.7)...

A agricultura familiar no Brasil é um dos segmentos de maior importância econômica e social do meio rural. Alicerçada por modestos investimentos em tecnologia, mão-de-obra e compra de insumos, responde por 38% da produção agrícola no país e 77% da mão de obra empregada no setor agrícola. Este trabalho teve como objetivo comparar duas metodologias de sistemas de suporte a decisão: AMC- Análise Multicritério e EMDS-Suporte à Decisão para Manejo de Ecossistemas, aplicadas para indicar a qualidade de terras para agricultura familiar, por meio da integração de macroindicadores ambientais, de infraestrutura e socioeconômicos. Os resultados foram validados pelos índices de qualidade dos assentamentos propostos por Sparovek (2003) e elaborados no âmbito do projeto...

Sazonalidade na composição botânica e produção de matéria seca, sob pastejo, em pastagem nativa, Pantanal - MS.
Provedor de dados: 14
Autores: CRISPIM, S. M. A.; SANTOS, S. A.; BARIONI JÚNIOR, W.; BRANCO, O. D.
As áreas de pastagem nativa de acordo com estudos da FAO(Organização das Nações Unidas para Agricultura e Alimentação), compreendem cerca de 70%, em todo o mundo. No Brasil, essas áreas perfazem 77%, constituindo um recurso importante na alimentação dos ruminantes domésticos e selvagens. No Pantanal, as pastagens nativas constituem a base alimentar da pecuária de corte, principal atividade econômica, cujo rebanho está estimado em 3 milhões de cabeças. Assim, a utilização correta das forrageiras nativas constitui um dos mais importantes aspectos do manejo da pastagem, e esta é obtida quando se combina a ecologia da natureza com a economia do homem, segundo Heady (1975). A vegetação é um dos componentes mais importantes do ecossistema (Araújo Filho et al.,...

Desempenho reprodutivo de cabras mestiças anglo-nubianas em três diferentes épocas de cobertura, no Acre.
Provedor de dados: 14
Autores: MAIA, M. da S.
Nas regiões tropicais, onde as condições climáticas são relativamente constantes o ano todo, e onde não ocorrem variações aparentes no fotoperíodo, a atividade reprodutiva dos caprinos se estende por todos os meses do ano. No entanto, a eficiência reprodutiva do rebanho resulta da interação entre o patrimônio genético do indivíduo e o meio ambiente. Desta forma, a manipulação do ambiente no sentido de oferecer aos animais melhores condições de manejo, resultará em maiores índices produtivos. O estabelecimento de uma estação de cobertura que contemple os eventos cobertura, parição e desmame com épocas que lhes sejam favoráveis, possibilitará ao criador a obtenção de uma maior produtividade do rebanho e, conseqüentemente, maior lucro com a exploração. Neste...

Autores: ANTONIOLLI, L. R.; LIMA, M. A. C. de.
O aspecto visual das frutas geralmente atrai a atenção do consumidor. Coloração característica e frescor são alguns atributos de qualidade que induzem o consumidor à primeira compra, mas que, isoladamente, não garantem as compras futuras. Isso significa que o consumidor deseja, além da aparência atrativa, que a fruta seja saborosa e, mais recentemente, que o seu consumo seja seguro e lhe traga benefícios à saúde através da ingestão de compostos nutracêuticos. O perfil do consumidor moderno está mudando e exigindo uma adequação do setor produtivo quanto ao fornecimento de alimentos livres de contaminantes que possam causar qualquer tipo de prejuízo à sua saúde. Nesse sentido, esta publicação busca apresentar uma síntese dos perigos potenciais associados à...

Mais pastagens, menos devastação: tecnologia permite redução de queimadas na formação de pastagens.

Autores: VALENTIM, J. F.
O estado do Acre, com 152.589 km2, tem como cobertura vegetal predominante a floresta tropical úmida aberta (77%) e densa (14%) (IBDF, 1984). A ocupação da Amazônia e do Acre, em particular, a partir da década de 60, tem sido um processo dirigido através de programas dos governos estadual e federal. Esta ocupação tem como objetivo resolver problemas de natureza social, econômica e política. A relativa escassez de conhecimentos científicos disponíveis sobre os mecanismos que garantem a sobrevivência da floresta pluvial tropical, predominante na região, está longe de permitir que se possa recomendar a exploração, em grande escala e ecologicamente segura, desse fantástico bioma.

Provedor de dados: 14
Autores: STUCHI, E. S.; GIRARDI, E. A.
A citricultura é uma das principais atividades do agronegócio brasileiro, estando presente em todas as regiões do país em diferentes ambientes de produção. A presença da doença huanglongbing (HLB), constatada no Brasil em 2004, vem provocando perdas expressivas em importantes regiões produtoras e colocando em cheque a sustentabilidade da cadeia citrícola. Estratégias de controle atual se baseiam no uso de mudas sadias, inspeção e erradicação sistemática de plantas sintomáticas e controle químico do inseto vetor. Pesquisas vêm sendo conduzidas pela Embrapa e outras instituições brasileiras com o objetivo de alcançar a resistência ao HLB por melhoramento genético via biotecnologia. Contudo, as limitações inerentes a essas ações determinam que proposições...

Autores: MARTINS, P. do C.; LANA, M. S.; CARNEIRO, A. V.
A produção mundial, que havia crescido 1,8% em 2015, em 2016 cresceu apenas 1,5%, provocando recuperação dos preços a partir de janeiro de 2017. Com média de US$ 0.35/kg no primeiro semestre, a expectativa é de que os preços mundiais não ultrapassem os US$ 0.37/kg até o final do ano. No Brasil, o preço médio real ao produtor nos últimos dez anos foi de R$ 1,30/litro (valores corrigidos pelo IPCA para julho de 2018), patamar 16% superior ao preço de referência mundial, de R$ 1,10/litro. Numa perspectiva da relação apenas do preço do leite e do concentrado: tomando como referência o consumo médio de um kg de concentrado para se produzir três litros de leite, o custo da ração representou R$ 0,30/litro. Esse indicador é em geral um pouco mais favorável ao...

Merchant ships discharging unwanted marine species in close proximity of a French aquaculture area: Risks involved
Provedor de dados: 5
Autores: Masson, Daniel; Thomas, Gerard; Genauzeau, Sylvie; Le Moine, Olivier; Derrien, Annick.
The most important oyster farming area in Europe is in a close proximity of two medium size merchant ports. Cargo ships deballast in this area before loading, releasing unwanted or noxious marine species. During a sampling campaign aboard these arriving ships, we found in some ballast water samples a huge number of potentially toxic dinoflagellates and some potentially pathogenic bacteria. A model was applied to find the potential geographical spread of the discharged ballast water. This model predicts the water to reach highly vulnerable shellfish farmed areas in six to eight days.

The dragon tamed? A molecular phylogeny of the Conoidea (Gastropoda)
Provedor de dados: 5
Autores: Puillandre, N.; Kantor, Yu. I.; Sysoev, A.; Couloux, A.; Meyer, C.; Rawlings, T.; Todd, J. A.; Bouchet, P.
The superfamily Conoidea constitutes one of the most diverse and taxonomically challenging groups among marine molluscs. Classifications based on shell or radular characters are highly contradictory and disputed. Whereas the monophyly of the Conidae and Terebridae has not been challenged, the other constituents of the superfamily are placed in a ‘trash’ group, the turrids, the non-monophyly of which has been demonstrated by anatomical and molecular evidence. We present here a new molecular phylogeny based on a total of 102 conoidean genera (87 ‘turrids’, 5 cones and 10 terebrids) and three mitochondrial genes [cytochrome oxidase I (COI), 12S rRNA and 16S rRNA]. The resulting tree recognizes 14 clades. When the Conidae (Conus s.l.) and Terebridae are ranked...

Sr‐Nd‐Hf isotopes along the Pacific Antarctic Ridge from 41 to 53°S
Provedor de dados: 5
Autores: Hamelin, Cedric; Dosso, Laure; Hanan, Barry; Barrat, Jean-alix; Ondreas, Helene.
Major, trace element and Sr-Nd-Hf isotope data in basalts collected along the Pacific-Antarctic Ridge ( PAR) axis between 53 and 41 S, far from any hotspot influence, reveal tight coherent geochemical variations within the depleted MORB mantle. All samples are located below the Pacific reference line defining two sub-oceanic mantle domains on each side of the Easter microplate. The data extend the PAR 66-53 S field towards more radiogenic Sr (0.70264), less radiogenic Nd (epsilon = 7.7) and Hf (epsilon = 11.4) values. The along ridge geochemical variability is closely related to the morphological segmentation of the ridge. Anomalous geochemical features are attributed to the atypical morphology of two segments due to the presence of off-axis magmatism. The...

Autores: Colombo, Francesca; Costa, Valentina; Dubois, Stanislas; Gianguzza, Paola; Mazzola, Antonio; Vizzini, Salvatrice.
Stable isotopes were used to investigate contributions of autochthonous (i.e. benthic: epilithon and macroalgae) and allochthonous (i.e. pelagic: phytoplankton) organic matter sources to the diet of suspension-feeders, grazers and predators associated to small reef-pools (cuvettes) created by the reef-building species Dendropoma petraeum in the north-western coast of Sicily (Italy). Contributions of potential food sources were calculated using Bayesian mixing-models and integrated to a multivariate approach to highlight the diversity of C and N pathways within Dendropoma cuvettes. Both pelagic and benthic organic matter sources were exploited by benthic consumers, although clear differences were revealed in the various species depending on their feeding...

In Vivo RNA Interference of a Gonad-Specific Transforming Growth Factor-beta in the Pacific Oyster Crassostrea gigas
Provedor de dados: 5
Autores: Huvet, Arnaud; Fleury, Elodie; Corporeau, Charlotte; Quillien, Virgile; Daniel, Jean-yves; Riviere, Guillaume; Boudry, Pierre; Fabioux, Caroline.
We investigated the role of oyster gonadal TGF beta (og-TGF beta) in the reproduction of Crassostrea gigas, using an in vivo RNA interference approach. We designed double-stranded RNA targeting og-TGF beta, which is specifically expressed in the somatic cells surrounding germ cells in the gonad of both male and female oysters. In vivo injection of this og-TGF beta dsRNA into the gonad led to knock-down phenotypes for both sexes, with significant reduction (77.52% relative to controls) of the gonad area, lowered reproductive effort and germ cell under-proliferation. Interestingly, half of the injected females halted their vitellogenesis, since we were only able to observe pre-vitellogenic oocytes. In addition, apoptotic germ cells and haemocytes infiltrated...

Autores: Sima, Laura C.; Schaeffer, Julien; Le Saux, Jean-claude; Parnaudeau, Sylvain; Elimelech, Menachem; Le Guyader, Soizick.
To evaluate membrane bioreactor wastewater treatment virus removal, a study was conducted in southwest France. Samples collected from plant influent, an aeration basin, membrane effluent, solid sludge, and effluent biweekly from October 2009 to June 2010 were analyzed for calicivirus (norovirus and sapovirus) by real-time reverse transcription-PCR (RT-PCR) using extraction controls to perform quantification. Adenovirus and Escherichia coli also were analyzed to compare removal efficiencies. In the influent, sapovirus was always present, while the norovirus concentration varied temporally, with the highest concentration being detected from February to May. All three human norovirus genogroups (GI, GII, and GIV) were detected in effluent, but GIV was never...

How trophic cascades and photic zone nutrient content interact to generate basin-scale differences in the microbial food web
Provedor de dados: 5
Autores: Thingstad, T Frede; Browman, Howard.
In linear food chains, resource and predator control produce positive and negative correlations, respectively, between biomass at adjacent trophic levels. These simple relationships become more complex in food webs that contain alternative food chains of unequal lengths. We have used a “minimum” model for the microbial part of the pelagic food web that has three such food chains connecting free mineral nutrients to copepods: via diatoms, autotrophic flagellates, and heterotrophic bacteria. Trophic cascades from copepods strongly modulates the balance between the three pathways and, therefore, the functionality of the microbial food web in services such as food production for higher trophic levels, DOM degradation, and ocean carbon sequestration. The result...

Operation and cleaning of ceramic membranes for the filtration of fish press liquor
Provedor de dados: 5
Autores: Perez-galvez, Raul; Guadix, Emilia M.; Berge, Jean-pascal; Guadix, Antonio.
This paper assesses the performance of three ceramic membranes of average pore size 50 nm, 200 nm and 1.4 tan in the treatment of the press liquor resulting from a compaction operation of sardine by-products. To this end, 2 L of pre-filtered press liquor with an average protein content of 44 g/L were filtered during 3 h through the three membranes assayed. Unexpectedly, the membrane of larger pore size, presented the lowest values for the flux of permeate at steady state at 20 L/(m(2) h), while its average protein rejection (77%) was similar to that observed in the membrane of 200 nm. This fact was attributed to the difference in material of its active layer (a-alumina instead of zirconite). The cleaning efficiency of the membranes was assessed by the COD...

Autores: Briant, Nicolas; Chouvelon, Tiphaine; Martinez, Laura; Brach-papa, Christophe; Chiffoleau, Jean-francois; Savoye, N.; Sonke, J.; Knoery, Joel.
Marine mercury (Hg) concentrations have been monitored in the French coastline for the last half a century using bivalves. The analyses presented in this study concerned 192 samples of bivalves (mussels: Mytilus edulis and Mytilus galloprovincialis and oysters: Crassostrea gigas and Isognomon alatus) from 77 sampling stations along the French coast and in the French Antilles sea. The goals of this study were to assess MeHg levels in various common bivalves from French coastline, and to identify possible geographic, taxonomic or temporal variations of concentrations. We show that the evolution of methylmercury (MeHg) concentrations covary with total mercury (HgT) concentrations. Moreover, in most of the study sites, HgT concentrations have not decreased...

We identified three new azaspiracids (AZAs) with molecular weights of 715, 815, and 829 (AZA33 (3), AZA34 (4), and AZA35, respectively) in mussels, seawater, and Azadinium spinosum culture. Approximately 700 mu g of 3 and 250 mu g of 4 were isolated from a bulk culture of A. spinosum, and their structures determined by MS and NMR spectroscopy. These compounds differ significantly at the carboxyl end of the molecule from known AZA analogues and therefore provide valuable information on structure-activity relationships. Initial toxicological assessment was performed using an in vitro model system based on Jurkat T lymphocyte cytotoxicity, and the potencies of 3 and 4 were found to be 0.22- and 5.5-fold that of AZA1 (1), respectively. Thus, major changes in...

A micro-sensor based on selenide glasses for evanescent wave detection in mid-infrared spectral range was designed and fabricated. Ge-Sb-Se thin films were successfully deposited by radio-frequency magnetron sputtering. In order to characterize them spectroscopic ellipsometry, atomic force microscopy and contact angle measurements were employed to study near and middle infrared refractive index, surface roughness and the wettability, respectively. Selenide sputtered films were micro-patterned by means of reactive ion etching with inductively coupled plasma process enabling single-mode propagation at a wavelength of 7.7 µm for a waveguide width between 8 and 12 µm. Finally, optical waveguide surface was functionalized by deposition of a hydrophobic polymer,...

Retrieval of Particulate Backscattering Using Field and Satellite Radiometry: Assessment of the QAA Algorithm
Provedor de dados: 5
Autores: Pitarch, Jaime; Bellacicco, Marco; Organelli, Emanuele; Volpe, Gianluca; Colella, Simone; Vellucci, Vincenzo; Marullo, Salvatore.
Particulate optical backscattering (bbp) is a crucial parameter for the study of ocean biology and oceanic carbon estimations. In this work, bbp retrieval, by the quasi-analytical algorithm (QAA), is assessed using a large in situ database of matched bbp and remote-sensing reflectance (Rrs). The QAA is also applied to satellite Rrs (ESA OC-CCI project) as well, after their validation against in situ Rrs. Additionally, the effect of Raman Scattering on QAA retrievals is studied. Results show negligible biases above random noise when QAA-derived bbp is compared to in situ bbp. In addition, Rrs from the CCI archive shows good agreement with in situ data. The QAA’s functional form of spectral backscattering slope, as derived from in situ radiometry, is...

Autores: Govenar, B; Le Bris, Nadine; Gollner, S; Glanville, J; Aperghis, A; Hourdez, S; Fisher, C.
The vestimentiferan tubeworm Riftia pachyptila (Polychaeta: Sibloglinidae) often dominates early succession stages and high productivity habitats at low-temperature hydrothermal vents on the East Pacific Rise. We collected 8 aggregations of R. pachyptila and the associated epifaunal community at 2 discrete sites of diffuse hydrothermal activity, in December 2001 and December 2002. Because of the high spatial and temporal variability of the biotic and abiotic factors related to hydrothermal vent activity, significant differences in the structure and the composition of the community were expected to occur at the scale of either 1 yr or 500 m distance between very different sites. There was no significant difference in the temperature ranges of the diffuse...

Fucoidans -- sulphated polysaccharides extracted from brown algae - could be beneficial in patients with ischemic diseases. Their antithrombotic and proangiogenic properties promote in animals, neovascularization and angiogenesis which prevent necrosis of ischemic tissue. In 1997, endothelial progenitor cells were first identified in human peripheral blood. They are recruited from bone marrow and contribute to neovascularization after ischemic injury. Mobilization of these cells in ischemic sites is an important step in new vessel formation. It is thought that the progenitors interact with endothelial cells, then extravasate and reach ischemic sites, where they proliferate and differentiate into new blood vessels. Although chemokines, cytokines and...

Long-term slip rates and fault interactions under low contractional strain, Wanganui Basin, New Zealand
Provedor de dados: 5
Autores: Lamarche, G; Proust, Jn; Nodder, Sd.
The newly mapped Kapiti-Manawatu Fault System (KMFS) in southern North Island, New Zealand, accommodated similar to 3.5 km of basement throw over the last 3 Myr. Along-strike throw profiles are generated using seven stratigraphic markers, interpreted from seismic reflection profiles acquired &lt; 3 km apart. The profiles are symmetrical about their point of maximum displacement, and cumulative profiles suggest that the reverse fault system behaves coherently. The KMFS originates from the reactivation of extensional structures, with fault lengths remaining constant over time. Contractional deformation started at circa 1750 +/- 400 ka. Maximum dip-slip rates along individual faults are 1.77 +/- 0.53 and 0.74 +/- 0.22 mm yr(-1) for the 0 - 120 and 120 - 1350...

Autores: Lacombe, Marielle; Garcon, Veronique; Thouron, Daniele; Le Bris, Nadine; Comtat, Maurice.
From the study of molybdenum oxidation in aqueous solutions we developed a semi-autonomous method to detect silicate in aqueous samples. Molybdenum oxidation was used to form molybdate in acidic media. The silicomolybdic complex formed with silicate is detectable by amperometry or cyclic voltammetry. The new electrochemical method is in good agreement with the method conventionally used for environmental water silicate analysis. In the second stage, a completely reagentless method was developed using molybdate and proton produced during molybdenum oxidation. Reproducibility tests show a precision of 2.6% for a concentration of 100 mu mol L-1. This new method will be Very Suitable for the development of new autonomous silicate sensors easy to handle and...

Water-soluble sulfated polysaccharides isolated from two red algae Sphaerococcus coronopifolius (Gigartinales, Sphaerococcaceae) and Boergeseniella thuyoides (Ceramiales, Rhodomelaceae) collected on the coast of Morocco inhibited in vitro replication of the Human Immunodeficiency Virus (HIV) at 12.5 mu g/mL. In addition, polysaccharides were capable of inhibiting the in vitro replication of Herpes simplex virus type 1 (HSV-1) on Vero cells values of EC(50) of 4.1 and 17.2 mu g/mL, respectively. The adsorption step of HSV-1 to the host cell seems to be the specific target for polysaccharide action. While for HIV-1, these results suggest a direct inhibitory effect on HIV-1 replication by controlling the appearance of the new generations of virus and...

Determining the lipid content and fatty acid (FA) composition of aquatic organisms has been of major interest in trophic ecology, aquaculture, and nutrition for over half a century. Although protocols for lipid analysis are well-described, their application to aquatic sciences often requires modifications to adapt to field conditions and to sample type. Here, we present the current state of knowledge of methods dedicated to both marine and freshwater lipid analyses, from sampling to data treatment. We review: (i) sample preservation, storage and transport protocols, and their effects on lipids, (ii) lipid extraction, separation of polar and neutral lipids, derivatization, and detection methods, and (iii) available tools for the statistical analysis of FA...

Provedor de dados: 5
Autores: Maalouf, Haifa; Schaeffer, Julien; Parnaudeau, Sylvain; Le Pendu, Jacques; Atmar, Robert L.; Crawford, Sue E.; Le Guyader, Soizick.
Noroviruses (NoVs) are the main agents of gastroenteritis in humans and the primary pathogens of shellfish-related outbreaks. Some NoV strains bind to shellfish tissues by using carbohydrate structures similar to their human ligands, leading to the hypothesis that such ligands may influence bioaccumulation. This study compares the bioaccumulation efficiencies and tissue distributions in oysters (Crassostrea gigas) of three strains from the two principal human norovirus genogroups. Clear differences between strains were observed. The GI.1 strain was the most efficiently concentrated strain. Bioaccumulation specifically occurred in digestive tissues in a dose-dependent manner, and its efficiency paralleled ligand expression, which was highest during the cold...

Are sex ratios in wild European sea bass (Dicentrarchus labrax) populations biased?
Provedor de dados: 5
Autores: Vandeputte, Marc; Quillet, Edwige; Chatain, Beatrice.
Sex ratios in farmed European sea bass are highly biased towards males (75 to 95%), which is problematic for aquaculture. In this mini-review, we re-analyse fisheries literature data about sex ratios in wild sea bass from 13 population samples, representing altogether 4889 individuals covering the major part of the distribution range of the species. We find that as a whole, the sex ratio of wild populations is biased towards females (59.4% females, p &lt; 0.001), but that the sex ratio of the younger fish (&lt; 30 cm total length) is balanced (52.0% females, p = 0.15), while the sex ratio of the older fish is heavily biased towards females (69.5% females, p &lt; 0.01). Possible causes of these differences (differential longevity, biased sampling) are...

The relative importance of environmental stochasticity, interspecific interactions, and observation error: Insights from sardine and anchovy landings
Provedor de dados: 5
Autores: Hosack, Geoffrey R.; Trenkel, Verena; Dambacher, Jeffrey M.
Long-term time series of sardine and anchovy landings often suggest negative dependence between these species, and an array of mechanisms have been proposed as explanations. We reduce these propositions to four basic hypotheses of (1) independence, (2) correlated process noise, (3) interspecific interactions, and (4) correlated observational error. We use a Bayesian approach to develop priors for parsimonious state space models with both process noise and observation error that represent each of these hypotheses, and apply this approach to five long-term time series of landings collected from the Pacific and Atlantic Oceans. Model comparison criteria suggest that the hypothesis of correlated process noise has the broadest support, where the temporal...

Remarques sur la sexualité de la sardine, clupea pilchardus walb.
Provedor de dados: 5
Autores: Belloc, G; Desbrosses, P.
During our studies on the biology of the sardine from the French Atlantic coast, over the 1929 fishery, we noticed some specificities in this fish's sexuality. In particular, we observed some differences between the male and female individuals from each of the studied batches. These differences are of the same order and show a constant character. Some sexual dimorphism facts tally with the fragmentary observations of L. Fage on the sardines from the entire French coast, Arné on the individuals caught South of the Gironde, and Le Gall on the celans from the English Channel. The observations we made can be used as a basis for a global study on the sexuality and the dimorphism in the sardine.

Residual transport velocities during winter, within the atlantis-ii deep area of the central red-sea
Provedor de dados: 5
Autores: Ahmad, F; Sultan, Sar; Moammar, Mo.
The Atlantis II Deep is located at about 21.5 degrees N within a deep trench which divides the Red Sea along the mid-axis. Data from the Atlantis II mooring, maintained during January-February 1978, provide valuable information about residual current distribution over the whole water column. The residual currents have speeds of 20 cm/s at the level of surface current meter, decreasing to 1.5 cm/s at about 250 m depth. The dominant direction over this depth level is southeast in January and changes to northeast in February. From 250 m down to the bottom the dominant direction is north-northwest and the residual speeds range between 1.5 and 3.0 cm/s at different depth levels. The weighted depth-mean residual current speed from surface to 250 m is about 7.7...

Phytoplankton fluorescence and deep chlorophyll maxima in the northeastern mediterranean
Provedor de dados: 5
Autores: Yilmaz, A; Ediger, D; Basturk, O; Tugrul, S.
Two expeditions in the northeastern Mediterranean by the R/V Bilim (in July 1988 and March 1989) scanned an area of about 3 x 10(5) km2 to determine, in situ, the relative fluorescence intensities of the upper layer waters. The in situ fluorescence intensities exhibited a fair correlation with the discrete chlorophyll-a concentrations when the concentrations exceeded 0.1 mug/L. Light intensities indicated that the euphotic zone had an average thickness of 100 m in the open waters. The deep chlorophyll-a maxima (DCM) at the bottom of the euphotic zone usually coincided with the maxima observed by in situ fluorometry and were a prevalent characteristic of the oligotrophic northeastern Mediterranean. The formation, maintenance and location of the DCM were...

Radiocarbon as a thermocline proxy for the eastern equatorial Pacific
Provedor de dados: 5
Autores: Rodgers, Kb; Aumont, O; Madec, G; Menkes, C; Blanke, Bruno; Monfray, P; Orr, Jc; Schrag, Dp.
An ocean model is used to test the idea that sea surface Delta(14)C behaves as a thermocline proxy in the eastern equatorial Pacific. The ORCA2 model, which includes Delta(14)C as a passive tracer, has been forced with reanalysis fluxes over 1948-1999, and the output is compared with a previously reported Galapagos Delta(14)C record. The model reproduces the abrupt increase in the seasonally minimum Delta(14)C in 1976/77 found in the data. This increase is associated with neither a shift of thermocline depth over the NINO3 region, nor a change in the relative proportion of Northern/Southern source waters. Rather, it is due to a decrease in the Sub-Antarctic Mode Water (SAMW) component of the upwelling water, thereby representing a decrease in entrainment...

Evolutionary history of Idas sp Med (Bivalvia: Mytilidae), a cold seep mussel bearing multiple symbionts
Provedor de dados: 5
Autores: Lorion, Julien; Halary, Sebastien; Do Nasciment, Joana; Samadi, Sarah; Couloux, Arnaud; Duperron, Sebastien.
Small mytilids of the genus Ildas are related to the large mussels found worldwide at deep-sea hydrothermal vents and cold seeps. They are therefore keys to a better understanding of the colonization of vents and seeps by symbiont-bearing organisms, but still little is known about their biology. For this study, specimens of a mytilid referred to the genus Idas were collected from various substrates in a cold seep area near the Nile deep sea fan. Based on molecular and morphological data, all specimens are confirmed to belong to a single species of the genus Idas, which was previously shown to host six distinct bacterial symbionts. Its larval shell characteristics indicate a long planktonic phase, which could explain its close relationship to a mussel...

Autores: Emerenciano, Mauricio; Cuzon, Gerard; Goguenheim, Jean; Gaxiola, Gabriela.
The floc system has been successfully applied for shrimp grow-out, but little is known about floc contribution on reproductive performance. In a 30-day trial, spawning performance of broodstock was evaluated in floc and earthen ponds. Floc spawners achieved better results (P &lt; 0.05) compared with pond spawners in terms of number of spawns per ablated female (2.9 vs. 1.3), spawns per spawning female (3.6 vs. 2.4) and number of consecutive maturation (average of 3.6 times compared with 2.5 times in ponds females). Latency period was lower for floc spawners (7.4 days) than pond spawners (10.7 days) (P &lt; 0.05). The percentage of females that spawned at least once were higher in floc (77.1%) when compared with pond spawners (53.8%) (P &lt; 0.05). Number...

Autores: Campillo, Albert; Regnault, M.; Luquet, P.
The evolution of nucleic acids in larvae of P. serratus reared in the laboratory from hatching to metamorphosis has been studied. From the 1st larval stage to the post-larval stage, DNA and RNA concn decrease: from 185 to 95 uMoles-bases/g PSD for DNA and from 133.5 to 78.75 uMoles-bases for RNA. The concn decrease is not regular; it is emphasized between stages 4 and 5 on the one hand, and between stage 7 and the post-larva on the other hand. The amount of DNA and RNA per larva increases proportionally to the wet weight from stage 1 to the post-larva. As the weight is multiplied by 7.6, total DNA and total RNA are multiplied by 3.80 and 4.25 respectively. The RNA/DNA ratio has a mean value of 0.77; it increases slightly from stage 1 (0.72) to the...

The effect of catch weight on trawl behaviour
Provedor de dados: 5
Autores: Priour, Daniel.
Measurements at sea during fishing trials on bottom trawl, have revealed that the geometry of the trawl is affected by the catch. A series of 27 hauls of around 3h have been carried out during the EFFICHALUT project. This project aimed to find out improvements on the fishing gear in order to reduce the energy consumption. For this project numerous sensors have been used, for bridles tension, doors spread, vertical opening, doors attitude. The measurements show quite clearly that the doors spread decreases and the bridles tension increases along most of the hauls. The doors spread decreases by 1.35m per hour, with a standard deviation of 1.98m/h when the top bridle tension increases of 47kg/h, with a standard deviation of 59kg/h. The mean catch per haul is...

Study yields surprises about seafloor spreading in back-arc basins
Provedor de dados: 5
Autores: Ruellan, Etienne; Lagabrielle, Yves; Tanahashi, Manabu; The Shipboard Party,.
A study of the seafloor in the North Fiji Basin is leading to a better understanding of the geometry and evolution of spreading in back‐arc basins. Two of the most important features of the area, the South Pandora Ridge and the Tripartite Ridge, belong to a presently active spreading system that began forming at least 7.2 m.y.a. The ridges spread at an average rate of about 1.6 cm/yr. By studying the segments of the ridges in greater detail, researchers found that each was either a “tectonic type,” with a more or less complex deep axial valley, or a “volcanic type,” with a high, rifted volcanic massif occupying the axial domain.

Feeding responses of hatchery-reared gilthead sea bream (Sparus aurata L.) to a commercial diet and natural prey items
Provedor de dados: 5
Autores: Andrew, J; Begout, Marie-laure; Kadri, S; Holm, J; Huntingford, F.
Many fish species have evolved feeding mechanisms and behaviours enabling them to feed on specific prey. However, such mechanisms may not be optimal for feeding on commercial-pelleted diets in aquaculture. Gilthead sea bream chew and occasionally eject pellets or parts of pellets from the mouth when feeding on commercial diets. This may result in an increase in nutritional waste from the intensive culture of this species. In this study we examined the prevalence of this food processing behaviour in two sizes of sea bream, feeding on three types of natural prey items in comparison to a commercial pellet, to give an insight into the circumstances in which excess chewing and ejection of food items from the mouth occurred. These included two hard-textured food...

Coastal hydrodynamics in a windy lagoon
Provedor de dados: 5
Autores: Alekseenko, Elena; Roux, Bernard; Sukhinov, A.; Kotarba, R.; Fougere, D.
The nonlinear hydrodynamics (3D RANS model) in a wide semi-enclosed windy lagoonal ecosystem is accurately investigated in the context of analyzing the limiting conditions of the recovery of submerged aquatic vegetation (SAV). Among the main natural hydrodynamical forcings, we consider the wind effect. We mainly focus attention to characteristic velocities (free surface and bottom) and to free surface elevation in the nearshore regions (with shallow water) where SAV were severely damaged in the past decades. Our main result relates to wind effects that form downwind coastal jets, alongshore, in shallow water areas, due to Berre bathymetry. Such coastal jets, which were never described previously in Berre lagoon literature, give rise to substantial bottom...

Marine landings in Portugal have decreased at a higher rate than fishing effort in the last 20 years. Identifying the variables driving the quantity and composition of landings is pivotal to understand the dynamics of the fisheries sector, which entails complex social and environmental aspects. In this study, we investigate the main drivers of marine fish landings in continental Portugal between 1989 and 2014. To identify common trends in time series, and quantify the importance of environmental factors, we applied a dynamic factor analysis considering four regions and three types of gear (trawling, purse-seine, and a multi-gear fishery). Our results show the importance of fishing effort as the most relevant factor driving marine landings in Portugal, both...

Toxicity to bivalve hemocytes of pathogenic Vibrio cytoplasmic extract

Autores: Lambert, Christian; Nicolas, Jean-louis; Bultel, Valérie.
Using a chemiluminescence (CL) test, it had been previously demonstrated that Vibrio pectenicida, which is pathogenic to Pecten maximus larvae, was able to inhibit completely the CL activity of P, maximus hemocytes and partially inhibit those of Crassostrea gigas, Conversely, a Vibrio sp, strain, S322, pathogenic to C,gigas larvae was more active in reducing the CL activity of oyster hemocytes than of scallop hemocytes, Using this same CL biotest, V, pectenicida and S322 cytoplasmic extracts were shown to reproduce CL inhibition while the cytoplasmic extract of a nonpathogenic strain (U1, Pseudoalteromonas) was without effect. Moreover, cytoplasmic extract as well as live V, pectenicida cells provoked, within a few hours, death of P. maximus hemocytes...

A new sea level observation network initiated by the World Ocean Circulation Experiment (WOCE) program is delivering hourly data from about 150 ocean stations worldwide. A complete analysis of these data was performed using a least squares method allowing better accuracy over time series virtually unlimited in time (up to 13 yr in this case). In addition to the classical tidal harmonic constants, the power density spectrum of the detided signal was computed. The 95% confidence intervals of the results of the analysis have been systematically estimated. The numerical and statistical methods applied to produce these numbers are presented for three stations as an illustration.

Integration of bioenergetics in an individual-based model to hindcast anchovy dynamics in the Bay of Biscay
Provedor de dados: 5
Autores: Bueno-pardo, Juan; Petitgas, Pierre; Kay, Susan; Huret, Martin.
The population of European anchovy of the Bay of Biscay collapsed at the beginning of the 21st century, causing the closure of its fishery between 2005 and 2010. In order to study both the human and environmental causes of the anchovy population dynamics, an approach coupling individual bioenergetics to an individual-based model was applied between 2000 and 2015. This modelling framework was forced with outputs from a physical–biogeochemical model. In addition to a base-case scenario with realistic forcing, alternative scenarios were run without inter-annual variability in either fishing mortality or environmental conditions. During the decrease in population biomass, a high fishing pressure coincided with a combination of environmental variables promoting...

Millennial to orbital-scale rainfall changes in the Mediterranean region and corresponding variations in vegetation patterns were the result of large-scale atmospheric reorganizations. In spite of recent efforts to reconstruct this variability using a range of proxy archives, the underlying physical mechanisms have remained elusive. Through the analysis of a new high-resolution sedimentary section from Lake Van (Turkey) along with climate modeling experiments, we identify massive droughts in the Eastern Mediterranean for the past four glacial cycles, which have a pervasive link with known intervals of enhanced North Atlantic glacial iceberg calving, weaker Atlantic Meridional Overturning Circulation and Dansgaard-Oeschger cold conditions.

Globally significant oceanic source of organic carbon aerosol
Provedor de dados: 5
Autores: Spracklen, Dominick V.; Arnold, Steve R.; Sciare, Jean; Carslaw, Kenneth S.; Pio, Casimiro.
Significant concentrations of organic carbon (OC) aerosol are observed at three oceanic surface sites (Amsterdam Island, Azores and Mace Head). Two global chemical transport models (CTMs) underpredict OC concentrations at these sites (normalised mean bias of -67% and -58%). During periods of high biological activity monthly mean concentrations are underpredicted by a factor of 5-20. At Amsterdam Island and Mace Head, observed OC correlates well (R-2 = 0.61-0.77) with back-trajectory weighted chlorophyll-a, suggesting an oceanic OC source driven by biological activity. We use a combination of remote sensed chlorophyll-a, back trajectories and observed OC to derive an empirical relation between chlorophyll-a and the total oceanic OC emission flux. Using the...

Quantifying connectivity within fish metapopulations is an important component in understanding population dynamics and providing an evidence base for assessment and management. We investigate meta-population connectivity of the common sole (Solea solea L.) in the Eastern English Channel (EEC). The EEC common sole stock is currently assessed as a single and spatially homogeneous population but connectivity induced through adult movements within this stock and with nearby stocks remains unknown. To fill this knowledge gap, we developed a state-space mark-recovery model, designed to estimate adult connectivity, using mark-recapture data from multiple release experiments from 1970 to 2018 across the EEC and adjacent management areas.

A data archeology exercise was carried out on sea level observations recorded during the transit of Venus across the Sun observed in 1874 from Saint Paul Island (38 degrees 41'S, 77 degrees 31 E) in the southern Indian Ocean. Historical (1874) and recent (1994-2009) sea level observations were assembled into a consistent time series. A thorough check of the data and its precise geodetic connection to the same datum was only possible thanks to the recent installation of new technologies (GPS buoy and radar water level sensor) and leveling campaigns. The estimated rate of relative sea level change, spanning the last 135 years at Saint Paul Island, was not significantly different from zero (-0.1 +/- 0.3mm yr(-1)), a value which could be reconciled with...

A new operational classification of the Conoidea (Gastropoda)
Provedor de dados: 5
Autores: Bouchet, P.; Kantor, Yu. I.; Sysoev, A.; Puillandre, N.
A new genus-level classification of the Conoidea is presented, based on the molecular phylogeny of Puillandre et al. in the accompanying paper. Fifteen lineages are recognized and ranked as families to facilitate continuity in the treatment of the names Conidae (for 'cones') and Terebridae in their traditional usage. The hitherto polyphyletic 'Turridae' is now resolved as 13 monophyletic families, in which the 358 currently recognized genera and subgenera are placed, or tentatively allocated: Conorbidae (2 (sub) genera), Borsoniidae (34), Clathurellidae (21), Mitromorphidae (8), Mangeliidae (60), Raphitomidae (71), Cochlespiridae (9), Drilliidae (34), Pseudomelatomidae (=Crassispiridae) (59), Clavatulidae (14), Horaiclavidae new family (28), Turridae s. s....

Provedor de dados: 5
Autores: Paquotte, Philippe; Bakela, Z; Franquesa, R; Basurco, B.
Aquaculture production in the Mediterranean showed a constant increase over the years. The current production reached 790000 Tm, in 1994. This represents about 5% of global aquaculture production. Although the Mediterranean aquaculture is moving mainly to shellfish (67.8%), fish production (31%) is increasing steadily. The production of marine fish is characterized by the dominance of two species, loubine and sea bream. These represent 35000 tonnes / year (...). [NOT CONTROLLED OCR]

Hindcasting the continuum of Dansgaard-Oeschger variability: mechanisms, patterns and timing
Provedor de dados: 5
Autores: Menviel, L.; Timmermann, A.; Friedrich, T.; England, M. H.
Millennial-scale variability associated with Dansgaard-Oeschger events is arguably one of the most puzzling climate phenomena ever discovered in paleoclimate archives. Here, we set out to elucidate the underlying dynamics by conducting a transient global hindcast simulation with a 3-D intermediate complexity earth system model covering the period 50 to 30 ka BP. The model is forced by time-varying external boundary conditions (greenhouse gases, orbital forcing, and ice-sheet orography and albedo) and anomalous North Atlantic freshwater fluxes, which mimic the effects of changing northern hemispheric ice volume on millennial timescales. Together these forcings generate a realistic global climate trajectory, as demonstrated by an extensive model/paleo data...

Archaeal Populations in Hypersaline Sediments Underlying Orange Microbial Mats in the Napoli Mud Volcano
Provedor de dados: 5
Autores: Lazar, Cassandre Sara; L'Haridon, Stephane; Pignet, Patricia; Toffin, Laurent.
Microbial mats in marine cold seeps are known to be associated with ascending sulfide- and methane-rich fluids. Hence, they could be visible indicators of anaerobic oxidation of methane (AOM) and methane cycling processes in underlying sediments. The Napoli mud volcano is situated in the Olimpi Area that lies on saline deposits; from there, brine fluids migrate upward to the seafloor. Sediments associated with a brine pool and microbial orange mats of the Napoli mud volcano were recovered during the Medeco cruise. Based on analysis of RNA-derived sequences, the "active" archaeal community was composed of many uncultured lineages, such as rice cluster V or marine benthic group D. Function methyl coenzyme M reductase (mcrA) genes were affiliated with the...

Biofouling development and its effect on growth and reproduction of the farmed pearl oyster Pinctada margaritifera
Provedor de dados: 5
Autores: Lacoste, Elise; Le Moullac, Gilles; Levy, Peva; Gueguen, Yannick; Gaertner-mazouni, Nabila.
In bivalve aquaculture, dominant fouling organisms are filter feeders which can compete for food with reared bivalves, sometimes causing mortality or reducing their growth rate. This study investigated the effect of biofouling on the farmed pearl oyster Pinctada margaritifera in two lagoons of French Polynesia. Survival, growth and reproduction of 2 year-old pearl oysters were monitored with regular sampling schedules, from the initial stage of colonization up to 20 months of biofouling accumulation. Control groups of pearl oysters were kept free of biofouling as is the current practice in pearl farms. After more than a year of monitoring, no significant difference was recorded in shell growth rate between pearl oysters reared with epibionts and the...

Modelling chance and necessity in natural systems
Provedor de dados: 5
Autores: Planque, Benjamin; Mullon, Christian.
Nearly 30 years ago, emerged the concept of deterministic chaos. With it came sensitivity to initial conditions, nonlinearities, and strange attractors. This constituted a paradigm shift that profoundly altered how numerical modellers approached dynamic systems. It also provided an opportunity to resolve a situation of mutual misunderstanding between scientists and non-scientists about uncertainties and predictability in natural systems. Our proposition is that this issue can be addressed in an original way which involves modelling based on the principles of chance and necessity (CaN). We outline the conceptual and mathematical principles of CaN models and present an application of the model to the Barents Sea food-web. Because CaN models rely on concepts...

Mayotte Island: another important green turtle nesting site in the southwest Indian Ocean
Provedor de dados: 5
Autores: Bourjea, Jerome; Frappier, Julie; Quillard, Mireille; Ciccione, Stephane; Roos, David; Hughes, Georges; Grizel, Henri.
Situated in the north of the Mozambique Channel, Mayotte is the easternmost island of the Comoros Archipelago. From 1998 to 2005, Grande Saziley beach was monitored daily for green turtle Chelonia mydas nesting activity. Track surveys were monitored daily on 5 other adjacent beaches. Although nesting occurs throughout the year, nesting seasonality begins at the end of the wet season and intensifies during the dry season to reach an average nesting peak in June. In order to estimate the number of females nesting in the Saziley site and population trends over the study period, incubation success and number of nests per female and per season were estimated at 0.77 (±0.05 SD) and 3.03 (±0.37) respectively. With an average of 1545 nesting turtles per year...

Autores: Collot, Julien; Migeon, Sebastien; Spence, G.; Legonidec, Y.; Marcaillou, B.; Schneider, J.-l.; Michaud, F.; Alvarado, A.; Lebrun, J.-f.; Sosson, M.; Pazmino, A.
cuador and southwest (SW) Colombia suffered widespread damage during the twentieth century as a result of some of the greatest subduction earthquakes and associated tsunamis ever recorded. In 1906, the Ecuador‐SW Columbia margin, located at the transition between the continent and deep ocean, ruptured over a 500‐kilometer length as a single great (Mw = 8.8) subduction earthquake (Figure 1a) [Kelleher, 1972]. The 1906 rupture zone was partially reactivated in 1942, 1958, and 1979 by earthquakes of Mw 7.7 to 8.2 (Figure 1b), with 100‐200 kilometerlong rupture zones [Beck and Ruff, 1984]. Such considerable variation in earthquake rupture length and magnitude in this area's seismic cycles during the last century has raised questions about the nature and...

Seasonal particulate carbon flux in the coastal northwestern mediterranean-sea, and the role of zooplankton fecal matter
Provedor de dados: 5
Autores: Fowler, Sw; Small, Lf; Larosa, J.
During a six-year (1978-1984) sediment trap study in the northwestern Mediterranean off the coast of Monaco, large variations in mass flux and carbon flux through 100 and 150 m were observed with maximum flux values occurring in late winter or early spring and minimum flux in late summer. Total particulate carbon flux was linearly related to mass flux. During March through October total particulate carbon flux represented, on average, approximately 7 % of the mass flux, whereas from November through February it averaged about 4.7 %. From recent organic carbon content data collected in the same region, it was estimated that approximately 5 % of the total mass flux through 100 and 150 m in calm seas was organic carbon (calm seas were prevalent during March...

Atmospheric drying as the main driver of dramatic glacier wastage in the southern Indian Ocean
Provedor de dados: 5
Autores: Favier, V.; Verfaillie, D.; Berthier, E.; Menegoz, M.; Jomelli, V.; Kay, J. E.; Ducret, L.; Malbeteau, Y.; Brunstein, D.; Gallee, H.; Park, Y. -h.; Rinterknecht, V.
The ongoing retreat of glaciers at southern sub-polar latitudes is particularly rapid and widespread. Akin to northern sub-polar latitudes, this retreat is generally assumed to be linked to warming. However, no long-term and well-constrained glacier modeling has ever been performed to confirm this hypothesis. Here, we model the Cook Ice Cap mass balance on the Kerguelen Islands (Southern Indian Ocean, 49 degrees S) since the 1850s. We show that glacier wastage during the 2000s in the Kerguelen was among the most dramatic on Earth. We attribute 77% of the increasingly negative mass balance since the 1960s to atmospheric drying associated with a poleward shift of the mid-latitude storm track. Because precipitation modeling is very challenging for the current...

Autores: Castilho,Marco Antonio Sant´Ana; Oda,Juliano Yasuo; Sant´Ana,Débora de Mello Gonçales.
La anatomía humana tiene como importante fuente de estudio al cuerpo humano. Ella utiliza cuerpos no reclamados, usualmente de indigentes, cuerpos entregados como un beneficio a la sociedad sin nada pedir nada a cambio, siendo dignos de pleno respeto. Sin embargo, preocupa que la muerte no es mirada socialmente como algo natural a la vida, llevando la convivencia en el laboratorio de anatomía humana a un estado de miedo, angustia y repulsión. Con eso se produce un mecanismo de negación, que puede generar deshumanización hacia la pieza anatómica. Ser confrontado con la muerte de otro, es lo mismo que confrontarse con nuestra propia muerte. En este contexto, los profesores y técnicos tienen una gran responsabilidad en discutir y reflejar la cuestión, de modo...

Predicting Horse Skin Weight from Carcass Weight
Provedor de dados: 77
Autores: Parés i Casanova,P. M.
A study was conducted to provide information on the skin weight of Pyrenean horses and to determine whether there is a measurement to predict this based on carcass weight. Hot carcass weight (HCW) and fresh skin weight (SW) were recorded for 58 horses aged 12 months entering a Catalan commercial slaughter facility between September 2009 and June 2010. Data on the breeder, age and coat characteristics were collected and subsequently collated for each animal. Prior to analysis, horses were subdivided into sex and coat groups. Data did not differ (P &lt; 0.001) among these. The absence of differences in SW could be viewed as a reflection of limited nutritional differences between seasons. Regression procedures were used to develop equations to predict SW from...

Placenta is the most accurate record of the infant prenatal experience. After delivery if the placenta is examined minutely, it provides much insight into the prenatal health of the baby and the mother. In diabetic pregnancy, placental weight is higher in comparison to normal pregnancy. To study the cellular differences that might contribute to larger size of placenta, light microscopic analysis was performed on 25 full term placentas, out of which 20 were of Gestational diabetes mellitus (12 controlled on diet, 8 controlled on insulin) and 5 control group. Tissue sections were processed and analyzed. Birth weight of neonate, placental weight, vascular pattern of chorionic blood vessels and site of attachment of umbilical cord were recorded. In the...

The Recurrent Laryngeal Cardiac Nerve in Fetuses
Provedor de dados: 77
Autores: De Gama,B. Z; Lazarus,L; Satyapal,K. S.
The recurrent laryngeal nerve has been reported to supply cardiac branches to the cardiac plexus. A review of anatomical literature on the existing term used to describe these branches revealed that varying interpretations and descriptions exist among various authors. Therefore, this study aimed to investigate the origin and incidence of branches from the recurrent laryngeal nerves to the cardiac plexus and their connections with sympathetic cardiac nerves. The sample comprised 40 cadaveric fetuses (n=80) (gestational ages: 16-30 weeks). The recurrent laryngeal cardiac nerve was described as the cardiac branch that originated directly from the recurrent laryngeal nerve and reached the superficial or deep parts of the cardiac plexus. This study found the...

En la literatura hay pocas citaciones sobre este músculo, más allá de la presencia de datos divergentes entre diversos autores. De este modo, el objetivo de este estudio ha sido el de analizar el músculo aductor mínimo con relación: a sus inserciones proximal y distal, a las disposiciones de las fibras musculares y establecer la incidencia del mismo. Cincuenta miembros inferiores aislados de cadáveres adultos de ambos sexos fueron disecados. Los resultados encontrados demuestran que el músculo fue observado en dieciséis casos (32%), presentando: inserción...

Differential Effect of the Route of Inoculation of Rabies Virus on NeuN Immunoreactivity in the Cerebral Cortex of Mice
Provedor de dados: 77
Autores: Rengifo,Aura Caterine; Umbarila,Vanessa Jazmin; Garzón,Mary Janeth; Torres-Fernández,Orlando.
Rabies is a lethal disease caused by a neurotropic virus that produces inconspicuous morphological changes hardly observable with conventional histopathology. The fatal outcome caused by rabies could be attributed to specific biochemical changes that severely impact neuronal function. The neuronal nuclear protein (NeuN) has become a widely used neuronal marker for the research and the histopathological diagnosis of nervous system diseases. To evaluate the distribution of the protein NeuN in the motor cortex of normal and rabies-infected mice adult ICR mice were inoculated with rabies virus either intramuscularly or intracerebrally. Rabies-infected mice were sacrificed at the terminal stage of the disease. Control mice were also euthanized at the same age....

Metallothionein: An Overview on its Metal Homeostatic Regulation in Mammals
Provedor de dados: 77
Autores: Sakulsak,Natthiya.
Metallothionein (MT) is a ubiquitous protein with a low molecular weight of 6-7 kDa weight and it was first identified in the kidney cortex of equines as a cadmium (Cd)-binding protein responsible for the natural accumulation of Cd in the tissue. The mammalian MT contains 61 to 68 amino acid residues, in which 18 to 23 cysteine residues are present. The expression of MT starts by binding of metal transcription factor-1 (MTF-1) to the regulative region of MT gene called metal responsive elements (MREs). The induction of MT through the MREs region can be initiated by several metal ions such as zinc (Zn), copper (Cu) and Cd. However, Zn is the only heavy metal which can reversibly and directly activate the DNA-binding activity of MTF-1. In mammals four types...

Autores: da Mata,João Roberto; da Mata,Fabiana Ribe; Aversi-Ferreira,Tales Alexandre.
Inadequate ossification of the interparietal region induces the appearance of interparietal and wormian bones, also associated with genetic factors. The formation of the interparietal bone depends on the separation of the intermediate segment from the lateral plate by the transverse occipital suture, which means that this bone is formed by the medial and lateral plates. Wormian interparietal bones or epactal bones are located within the interparietal region, being single or multiple, and are located in the upper central region of the interparietal region, the sutural bones, however, are formed from additional ossification centers that can occur in near sutures. The aim of this work was to macroscopically evaluated the presence of changes in the structure...

Impronta Genómica y Desarrollo Embrionario
Provedor de dados: 77
Autores: Reig,German; Concha,Miguel L.
En los organismos diploides, cada gen autosómico está representado por dos copias, o alelos, heredados de cada progenitor al momento de la fecundación. Para la gran mayoría de los genes la expresión ocurre desde ambos alelos de manera simultánea. Sin embargo, un número reducido de genes (menos del 1%) es afectado por un proceso de impronta genómica. Este proceso determina que la expresión del gen sea dependiente del origen parental, es decir, se comporte de manera distinta si su origen es materno o paterno. La metilación del ADN es una de las modificaciones epigenéticas mejor estudiadas y su participación resulta esencial durante el establecimiento de la impronta genómica. Si bien los patrones de metilación a nivel genómico son estables y heredables,...

Piriformis muscle syndrome has been increasingly recognized as a cause of leg pain. Overuse, strain, or anatomical variations of the relationship between the nerve and the piriformis muscle are thought to be the underlying causes of the entrapment of the sciatic nerve. We report a variation not previously described which was found during a routine dissection. During routine dissection of the left gluteal region of an adult male cadaver we observed a high division of the sciatic nerve and the presence of an accessory piriformis muscle. The sciatic nerve divided beneath the piriformis muscle and the common fibular nerve passed over the accessory piriformis muscle, whereas the tibial nerve reflected anteriorly to pass between the accessory piriformis and the...

Autores: Vasconcellos,Adriana; Cisternas,Carla; Paredes,Marco.
La asociación de factores genéticos, nutricionales y ambientales afecta directamente la fertilidad de las ovejas sin embargo en condiciones de similitud ambiental, la raza es un factor determinante existiendo razas de alta fertilidad como por ejemplo Texel y Suffolk y otras de fertilidad estándar tales como Romney y Criolla Araucana. La fertilidad es modulada por las hormonas sexuales que actúan mediante la unión a receptores específicos. En ovinos el receptor de estrógeno alfa (ER-a) esta ampliamente distribuido en el sistema reproductivo y es responsable de la modulación de varios mecanismos asociados con la función del sistema reproductivo. Un factor posiblemente relacionado con la diferencia en la fertilidad entre razas de ovinos, es el nivel de...

Provedor de dados: 77
Autores: Hong,Xiao; Zhang,Ru; Pan,Hongying; Zhang,Wanmei; Hu,Tao.
Irregular root configurations which often challenge the requirements of successful root canal treatments are always misleading doctors to incorrect clinical judgments and treatment planning. In this article we describe a rare case of CBCT C-shaped mandibular premolar with a huge area of invagination measuring 6 mm ´ 3 mm, which we termed a "radicular rift valley" from a 76-year-old man. Considering the complex process of differential diagnosis, the overall status of disease condition and the will of the patient we proposed five treatment plans and finally conservatively chose plan B composed of both RCT and periapical scaling. A related literature review is also added into this article to describe the whole situation of root invagination, to stress the...

Autores: Yu,Ming-Yang; Zhang,Wei; Zhang,De-Bao; Zhang,Xiao-Dong; Gu,Gui-Shan.
Purpose: There is a paucity of data which reflected the relationship between morphology and incidence of shoulder disorders with respect to the ethnic Chinese population. We used anteroposterior radiographs to measure the Acromion Index (AI) and Acromioglenoid Angle (AA) of Chinese patients. The baseline was defined as the line that connected the superior and inferior osseous margins of the glenoid cavity. In order to calculate the AI, the distance from the baseline to the lateral margin of the acromion was measured and then divided by the distance from the baseline to the lateral aspect of the humeral head. The AA was defined as the angle formed by the intersecting line drawn tangent to the sclerotic line of the acromion undersurface and the baseline...

The Qualitative Effects of Resveratrol and Coenzyme Q10 Administration on the Gluteus Complex Muscle Morphology of SJL/J Mice with Dysferlinopathy
Provedor de dados: 77
Autores: van der Spuy,Wendy Jeannette; Pretorius,Etheresia.
Dysferlinopathy is a form of muscular dystrophy affecting muscles of the shoulder and pelvic girdles, resulting from inheritance of a mutated dysferlin gene. The encoded dysferlin protein is proposed to be involved in sarcolemmal vesicle fusion with a disrupted plasma membrane; however, with defective protein function these vesicles accumulate beneath the disruption site but are unable to fuse with it and reseal the membrane, thus rendering the membrane repair mechanism defective. The SJL/J mouse model presents with characteristics much like the commonest human condition. Immune modulators have long been under study in the maintenance of muscle health in muscular dystrophies. Such supplementary treatment would ideally suppress inflammation, preventing the...

Origin, Evolution and Homologies of the Weberian Apparatus: A New Insight
Provedor de dados: 77
Autores: Diogo,Rui.
The Weberian apparatus is essentially a mechanical device improving audition, consisting of a double chain of ossicles joining the air bladder to the inner ear. Despite being one of the most notable complex systems of teleost fishes and the subject of several comparative, developmental and functional studies, there is still much controversy concerning the origin, evolution and homologies of the structures forming this apparatus. In this paper I provide a new insight on these topics, which takes into account the results of recent works on comparative anatomy, paleontology, and ontogeny as well as of a recent extensive phylogenetic analysis including not only numerous otophysan and non-otophysan extant otocephalans but also ostariophysan fossils such as...

The aim of this study was to investigate the anatomy of the maxillary artery (MA) and its branches. Fourteen sides of Turkish adult cadavers were dissected. The specimens were classified according to the relation between MA and the lateral pterygoid. After the removal of the lateral pterygoid, parts and branches of MA were exposed. We classified the branching patterns of MA in the pterygopalatine fossa. The calibers and lengths of the arteries, and the distance between the zygomatic arch and MA, and between the infratemporal crest and MA were measured. The MA was found superficial to the lateral pterygoid in 57.2%. The inferior alveolar artery (IA) was arisen from MA before the middle meningeal artery (MM) in 35.7%, after MM in 35.7%. The IA and MM were...

Autores: Meng,Shaoquan; Bei,Yongjian; Li,Guifen; Lu,Ronghui; Qi,Baomin; Wu,Defeng.
The gills of Ichthyophis bannanicus have yet to be investigated. This paper describes the external morphological features of the gills of mature I. bannanicus embryos exhibiting three pairs of gills on their neck region. Each gill is composed of an axis and filaments. In newly released embryos, the filaments and the axis form at approximately 90° relative to each other; eventually, this angle decreases and the color of the gill fades. The filaments on the axis are arranged alternately, and their spacing varies. The mid-pair of gills is significantly longer by nearly twofold than the front and rear pairs. Likewise, the lengths of the front and rear pairs of gills are not significantly different (P &amp;gt;0.05); for the same pair of gills, the lengths of...

La vasculogénesis es controlada por una serie de mecanismos que se activan en función del tiempo y del espacio durante el desarrollo embrionario. Múltiples son las vías de señalización implicadas en las etapas del proceso vasculogénico, las que se inician con estímulos angiogénicos desde el mesodermo o desde el endodermo para dar origen a los angioblastos (células progenitoras endoteliales). Proteínas como el factor de crecimiento vascular endotelial (VEGF), factor de crecimiento fibroblastico 2 (FGF2), entre otras, constituyen factores claves en la inducción de este proceso. Posteriormente, los angioblastos deben migrar para dar origen a los vasos primitivos, proceso en el que participan factores atrayentes y repulsivos que orientarán la dirección de su...

Autores: del Sol,Mariano; Vásquez,Bélgica.
The anatomical variation of the major pectoral muscles is infrequent, namely the agenesis of the pectoralis major muscle due to the morpho-functional alterations it causes. On the other hand, he presence of -supernumerary - pectoral muscles is not common and its physiological, clinical or surgical importance will depend on the stage of its development. The important aspect is that these muscles, while crossing the anterior wall of the axila and inserting in the humerus, may confuse or difficult surgical access to the content of the axillary fossa. Pectoralis tertius muscles were found in two dissected cadavers at the Topographic Anatomy of the Faculty of Medicine of the Universidad de La Frontera, Chile.

Proximal Femoral Epiphysis Anatomy in Chilean Population: Orthopedic and Forensic Aspects
Provedor de dados: 77
Autores: Osorio,Horacio; Schorwer,Karl; Coronado,César; Delgado,Javier; Aravena,Pedro.
From a biomechanical standpoint, bone geometry and density are factors correlated to the bone resistance of the femur when supporting body weight, with geometric parameters like the diameter of the femoral head and neck, the length of the femoral neck, and the femoral neck angle as determinant factors in the incidence of hip fractures, which increase in frequency and seriousness in osteoporotic patients. In Chile, morphometric data that contributes to relating the anatomy of the proximal epiphysis of the femur as an associated factor in hip fractures does not exist; likewise, there are no anthropometric indexes that may contribute to the forensic sciences. The purpose of this study is to establish average measurements of the proximal epiphysis of the femur...

Provedor de dados: 77
Autores: Sidorkewicj,Nora S; Casanave,Emma B.
Middle ears of adult Chaetophractus villosus, C. vellerosus and Zaedyus pichiy were studied for qualitative and quantitative comparisons. A great similarity in the overall shape of the middle ear structures was observed in the three species. The well-developed auditory bulla was formed by the intimate fusion of the tympanic and entotympanic. Internally, a recessus meatus and a wide epitympanic recess extending dorsally into an epitympanic sinus were recognized. The petrosal promontorium, nearly triangular, was the most salient feature in the tympanic cavity. The auditory ossicles corresponded to the transitional middle ear type. The m. tensor tympani and the m. stapedius were conspicuous. The lack of a stapedial artery was confirmed in all cases. The...

Autores: Joshi,S. S; Joshi,S. D; Kishve,P. S.
The large size of superficial group of muscles of back of leg is a characteristic feature of the musculature of man being related directly to its erect posture and mode of progression. Triceps surae is one of the powerful muscles of the body after Gluteus maximus and Quadriceps femoris. To make the muscle more powerful nature has devised a unique method of packing the fibers in a small space by pennation. There exists a bipenniform mass as a peculiarly human feature. Its feathered fasciculi arise from the deep (anterior) surface of the soleus muscle. Most of the textbooks of Anatomy and the available literature on the triceps surae or the tendoachillis do not appreciate and describe this fascinating aspect of the muscle. It was Schafer et al. (1923) who...

Interparietal Bone Variations in Accordance with their Ossification Centres in Human Skulls
Provedor de dados: 77
Autores: Khan,Aaijaz Ahmed; Ullah,Muzammil; Asari,Mohd. Asnizam; Hassan,Asma.
The upper interparietal segment of the squamous part of the occipital bone develops in membrane and the lower supraoccipital part develops in cartilage. According to the available literature, the interparietal segment is ossified from 2 to 3 pairs of ossification centres and each of these centres has 2 nuclei. Interparietal bone is formed due to failure of fusion of these centres and/or their nuclei with each other. Many variations of interparietal bone have been reported by many investigators. In the present study, out of 25 human skulls studied, six skulls had some interesting variations of interparietal bones. Four interparietal bones were found in one skull, 2 interparietal bones were observed in another skull and the remaining four skulls had a single...

Obesity has reached epidemic proportions, the World Health Organization (WHO) estimates that there are more than 1,000 million overweight adults world-wide. Furthermore, obesity is characterized as an overgrowth of white adipose tissue as a result of adipocyte hypertrophy and hyperplasia. Mitochondria is considered the source of energy within the adipocyte, since it contains the molecular machinery, and it is involved in a large number of metabolic pathways, besides the transformation of chemical energy into adenosine triphosphate. Mitochondria shortage and adipocyte dysfunction result in an excessive accumulation of triacylglycerol in the cytoplasm, which determines an imbalance between energy production and energy expenditure. Resveratrol (RSV) is a...

Autores: Sanchis,E. G; Cristofolini,A. L; Taglialegna,A; Merkis,C. I.
The molecules that constitute the extracellular matrix are important in several functions related to tissue support and cell-cell, cell-extracellular matrix interaction. Among the macromolecules that constitute the mentioned matrix we find osteopontin, fibrinogen and collagen. The present study was undertaken to analyze the rol of osteopontin, fibrinogen and collagen in uterine-placental interface during normal porcine gestation. Uterine and placental tissues from crossbred gilts of 30 (n=5), 60 (n=5), 70 (n=5) and 114 (at term, n=5) days of gestation were used. Macroscopic analysis of the embryos/fetuses allowed us to determine their gestational age by means of the crown-rump lenght. Haematoxylin-Eosin and Masson's Trichrome dyes along with light...

Provedor de dados: 77
Autores: Dave,Mitesh R; Yagain,Vaishali Kiran; Anadkat,Samir.
Pain is a common distressing symptom in dental practice. Depending upon the cases, different techniques are used to relieve pain. One of these is peripheral trigeminal nerve block. Peripheral trigeminal nerve block anaesthesia has proved to be an effective and convenient way to anaesthetise large regions of oral and maxillofacial complex. This block can be intraoral or extra oral. The intraoral route is through the greater palatine foramen in which the dental surgeons enter into the pterygopalatine fossa, where the maxillary nerve is situated. The morphological variations in the position of greater palatine foramen may be of clinical importance in the administration of local anaesthesia and in palatal surgery. In the present study, the distance of greater...

A New Quantitative Method for Predicting Forensic Racial Identity Based on Dental Morphological Trait Analysis
Provedor de dados: 77
Autores: Alsoleihat,Firas.
Few previous studies have demonstrated the likelihood of using the worldwide patterns of dental morphological variation in prediction of ancestry in the context of forensic dental anthropology. This paper introduces a new quantitative method for predicting forensic racial identity of individual specimens based on dental morphological trait analysis. In this study, the inter-population variation in the expression frequency of 16 non-metric tooth crown traits, manifested on the permanent dentition, was used for analysis. The method was developed from the notion that dental morphological characteristics, when viewed as sets of traits rather than isolated variables, can be utilized to calculate the relative probability that an individual belongs to a...

Problem based learning (PBL) made a great impact on the methodology of teaching. The major advantage of PBL method of teaching is integration of basic and clinical sciences in an integrated curriculum. This is achieved by presenting clinical problems to students which contain learning objectives from subjects related to the given clinical problems. In recent reports deficiencies have been reported regarding quantity of anatomy content of the clinical problems which has resulted in difficulty in understanding of theanatomy. We have made an attempt to quantify the content of anatomy and its sub-disciplines in PBL curriculum by a case study method using 'documentary analysis' at School of Medicine and Health Sciences, UCSI University, Kuala Lumpur, Malaysia....

Also, we wanted to determine whether there are significant differences in the observed parameters between subjects in relation to age. The main criterion for the selection of test subjects is that they are unemployed. This is because we felt that those persons have more free time for practicing sports and recreational activities, and there is a very small number of studies in the area of Tuzla Canton with the characteristics of the sample. For the purpose of this research we applied analysis of percentage/ratio, t-test for independent samples and the Mann-Whitney U Test. Applied analysis showed that the increased...

Provedor de dados: 77
Autores: Mutua,P. M; Gicheru,M. M; Makanya,A. N; Kiama,S. G.
In mammals, surface respiratory macrophages (SM) are known to play a foremost role in protecting the respiratory system by providing first line of defense through engulfing pathogens and particulate matter respired with air. It has been reported that the pulmonary cellular defense system of domestic birds is inadequate. In particular, low number of SM and even lack of the cells in a healthy avian respiratory system have been associated with susceptibility of domestic birds to respiratory diseases. In an endeavor to resolve the existing controversy, the quantitative and qualitative attributes of the surface respiratory macrophages of the domestic duck and of the domestic rabbit were compared under similar experimental conditions. Quantitatively, the rabbit...

Autores: Ghosh,Susmita; Mandal,Lopamudra; Roy,Sanchita; Bandyopadhyay,Manimay.
Human anatomy is an ocean of unending variations and its mysteries are being unravelled since ages. Knowledge of variations in the superficial veins of head and neck is essential to carry out successful surgical procedures. During routine dissection of head and neck of two middle aged male cadavers, in the Department of Anatomy, Calcutta National Medical College, Kolkata, India, we came out with some interesting venous architecture. The retromandibular vein on the left side of both the cadavers was found to be undivided and joined with the facial vein in the neck at an acute angle to form a common venous trunk at variable distances from the angle of the mandible. That trunk ultimately drained into the left subclavian vein. This might be the result of...

Autores: Ramirez,Daysi; Gajardo,Carolina; Caballero,Paula; Zavando,Daniela; Cantín,Mario; Suazo Galdames,Iván.
The fibularis tertius muscle (FTM) in man has been developed over time to acquire subsequent bipedal gait. The FTM functions as a crucial contributor in dorsiflexion and eversion, postulated over the years as a stabilizer of the talocrural joint, avoiding forced investment and protecting the anterior talofibular ligament. The literature describes that FTM is absent in 10% of cases, with no data on Chilean population. A study of surface anatomy in 168 young subjects, 60% female and 40% male students at the Universidad de Talca, Chile, with a mean age of 20.6 ± 1.68 years, was conducted. The presence of FTM was identified following the implementation of a clinical assessment protocol that determines the presence of muscle on the basis of a progression called...

This study aimed to bring the trapezius muscle, knowledge of the locations where the accessory nerve branches enter the muscle belly to reach the motor endplates and find myofascial trigger points (MTPs). Although anatomoclinical correlations represent a major feature of MTP, no previous reports describing the distribution of the accessory nerve branches and their anatomical relationship with MTP are found in the literature. Both trapezius muscles from twelve adult cadavers were carefully dissected by the authors (anatomy professors and medical graduate students) to observe the exact point where the branches of the spinal accessory nerve entered the muscle belly. Dissection was performed through stratigraphic layers to preserve the motor innervation of the...

Autores: Renfeng,Li; Xiangqin,Tian; Songlin,Qiao; Yanyan,Yang; Enmin,Zhou; Gaiping,Zhang.
Microfold (M) cells act as antigen-sampling sites for initiating antigen specific mucosal immune responses, but they may also provide a gateway for enteropathogen entry. In this study we demonstrated villous M cells by morphological and immunohistochemical methods to be present in the three regions of the small intestine from newborn piglets. Immunohistochemical analysis, using anti- cytokeratin 18 (CK18) primary antibodies, showed a gradually decreased density of M cells from the lower crypt epithelium to the upper villous epithelium. The proportion of villous M cells was greater in the ileum than in the duodenum or the mid-jejunum. Ultrastructural observation revealed that villous M cells were mainly columnar in shape in the duodenum and the mid-jejunum,...

We studied the effects of a severely hypoproteic diet on the quantitative aspects of the myenteric plexus of the descending colon of young rats. Eighteen rats were divided into two groups, one of them being fed with a chow having 26% protein (control) and the other with a chow having 4% protein, balanced for minerals and vitamins, during 12 weeks. The whole-mounts of the descending colon had their myenteric neurons stained either with Giemsa or NADPH diaphorase. The rats from the experimental group had deficits of body weight (54.23%) and area of the descending colon (48.14%); additionally, we observed that there was no alteration in the total number of neurons of the colon, but a decrease in the number of NADPH-diaphorase positive neurons (37.80%).

The Asymmetry and Modularity of the Hyoid Bone
Provedor de dados: 77
Autores: Urbanová,Petra; Hejna,Petr; Zátopková,Lenka; Safr,Miroslav.
Morphological variation is a result of interplay among multiple intervening factors. For hyoid bones, the shape and size differences have been scarcely covered in the literature and in majority limited to studies of sexual dimorphism or age dependency. To our knowledge, the human hyoid bone, in complete opposite to other cranial bones, has not been fully utilized to address development questions in terms of asymmetry or modularity. In the present paper, we used landmark-based methods of geometric morphometrics and multivariate statistical approach to study human hyoid morphology represented by the hyoid body and greater horns in a sample of 211 fused and non-fused bones. Within a sample variation analysis, we showed that the hyoid bone is, by nature,...

Autores: Beu,Celia C. L.; Orsi,Antonio M; Domeniconi,Raquel F; Novelli,Ethel L. B.
The concentration of total protein measured by photocolorimetric methodology and reported as units per 100 mg of tissue decreased from the initial segment to the cauda epididymidis of the Golden hamster, being significant the numeric difference observed between these two regions. This observation was related with an increased synthesis and secretion of proteins to the lumen in proximal segments of the epididymidis duct, mainly in initial segment, as proposed for other rodents. LDH activity was higher in initial segment and distal cauda than in the caput and corpus epididymidis, although no significant differences in mean values had been observed. The high LDH activity observed in initial segment and cauda epididymidis of hamster had been related to an...

Morphostructural Relationships and Productive Functionality of Sheep Breeds Used for Terminal Crossbreeding in Chile
Provedor de dados: 77
Autores: de la Barra,R; Martínez,M. E; Carvajal,A.
The body shape of an animal population determines ranges of biological functionality and productive use. In sheep, meat productivity is closely related with the body size of the animal. Some sheep breeds are used in terminal crossbreeding to give the lamb favorable dimensional characteristics, but it is necessary to go deeper on the study of the relationships between morphostructure and productive aptitude of these breeds, since discrepancies could be due to the environmental effects or the degree of differentiation between the original pool of different breeds and the local populations. The study aimed to evaluate the morphostructural characters in four sheep breeds in Chile and discuss their relationship with the productive functionality of the body...

Provedor de dados: 77
Autores: Ortega-Martínez,Marta; de-la-Garza-González,Carlos; Ancer-Rodríguez,Jesús; Jaramillo-Rangel,Gilberto.
It is considered that healthy adult cartilage has little or no capacity for renewal, and that chondrocytes maintain a stable resting phenotype and resist proliferation and differentiation throughout life. Recently we found that cell turnover in lung cartilage is possible and that nestin-positive cells may have a role in it. In this paper, we report additional findings about chondrocyte renewal in lung cartilage. Lung specimens from CD1 mice at the age of 2, 6, 12, 18 or 24 months were fixed in 10% neutral-buffered formalin and paraffin-embedded. Nestin expression was examined by an immunohistochemical peroxidase-based method. We found nestin-positive cells inside of cartilage islets and cells in division very close from them. Our findings indicate that...

Provedor de dados: 77
Autores: Aktas,Ranan Gulhan; Karabay,Gulten; Taskinalp,Oguz; Kutlu,A. Kemal.
Although the structure and the functions of juxtaglomerular cells (JG) have been well defined, there is still a controversy about the secretory mechanisms of renin from these cells. It has been assumed that exocytosis is the main secretory mechanism in these cells in many studies, while others suggest that secretion occurs in a quite different way in these cells. There are several studies suggesting that diacrine secretion, which is very difficult to visualize, might be the other mechanism for secretion of renin. This study is an attempt to find the answers of these questions by identifying the fine structural features of the secretory granules in juxtaglomerular cells. Cyclosporin A (CyA) has been used in the current experimental study since it has...

The apoptosis phenomenon happens in normal tissues and in many pathological conditions as described by several researchers. Most studied in the 70s, this phenomenon remained almost forgotten in the 90s, when, with the advent of more advanced techniques, returned to laboratories. Thus, electronic microscopy, Comet Assays and histochemistry techniques, among others, were utilized in an effort to elucidate in a thorough way, the mechanisms that lead the cell to "suicide". No one can deny the importance of the knowledge of such phenomenon, so as to control its induction or blocking in the treatment of pathologies such as cancer. In this work, the apoptosis study was aimed at denervated muscles in different periods. Furthermore, two types of skeletal striated...
